FAQs: Mounting Brackets for Fuel Cell System Applications
In fuel cell systems, mounting brackets perform the function of primary support structure for the fuel cell stacks, which weigh between 80 and 250 kg and generate between 80 and 150 kW for passenger vehicles and 200 to 400 kW for commercial trucks, 4 to 10 kg of hydrogen storage tanks at 350 to 700 bar pressure, and balance-of-plant components like air compressors and coolant pumps, along with the electronics for the power distribution. Mounting brackets handle and support the static loads between 500 and 3000 N and dynamic loads in the automotive context, which include vibrations of 5 to 20 g and shock loads of 30 to 50 g. Mounting brackets are stack mounting frames (400 to 800 mm long) which provide compression force of 20 to 100 kN and transmission of that force through isolation mounts, tank cradle brackets which secure cylindrical vessels (300 to 500 mm diameters) with retention (21 to 40 kN) straps, and isolation mounting brackets that support active anti-vibration systems using elastomeric bushings that attenuate vibrations in the 10 to 2000 Hz range with over 60% isolation efficiency.
Within automotive environments, stainless steel 304 has exceptional corrosion resistance where salt water is exposed, possesses sufficient strength with having yield strength between 215 and 310 megapascals for supporting loads between 500 and 5000 newtons, and has good weldability to form bracket assemblies with joint efficiency between 80 and 95 percent. Aluminum 6061-T6 has the best strength-to-weight ratio, which is one of the biggest factors for reducing the weight of brackets by 40 to 60 percent and by improving vehicle efficiency since its yield strength is 276 megapascals and its density is 2.7 grams per cubic centimeter. It also has exceptional machinability and formability for the production of complex designs, and has superior corrosion resistance when anodized. AHSS for high-strength steel provides the utmost load capacity with yield strength between 550- 980 megapascals, which leads to lightweight designs and routines where the thickness of the steel is 2- 4 millimeters and can support the same load as conventional steel with the thickness of 4- 6 millimeters. This is a reduction of 30- 50 percent in weight.
Laser cutting processes, both fiber and CO2, are used to produce mounting brackets from sheets of metal that are 2 to 8 millimeters thick. Edge quality is maintained at less than 3.2 microns, and laser cutting achieves an accuracy of ±0.010 inches. CNC press brake bending reduces required manual labor, and forms mounting flanges and reinforcement ribs. Press brake bending achieves an angle accuracy of ±0.5 degrees and a repeatability of ±0.015 inches. Robotic MIG and TIG welding comply with the requirements that the weld penetration must be 2 to 5 millimeters, and the weld shall have a tensile strength of 80 to 95 percent of the strength of the parent material. CNC drilling and CNC tapping are used to prepare mounting brackets with M6 to M12 holes while achieving a position accuracy of ±0.008 inches. Powder coating achieves an epoxy and polyester finish of 60 to 100 microns thick. The finish achieves a corrosion resistance of 1000 hours of salt spray per ASTM B117 with a thickness of 60 to 100 microns.
We achieve tolerances of ±0.015 to within the overall bracket dimension on assemblies for the range of 300 to 800 millimeters for ensured vehicle integration. Mounting bracket positions on bolt patterns of 200 to 600millimetersr are accomplished within alignment of the chassis mounting points to within ±0.008. For uniform load distribution, tolerances on flatness are achieved within 0.01 on mounting surfaces of 100 to 400 millimeters. For bend dimensions with consistency, ±0.5 bend angle tolerances are achieved with 0.020 for perpendicularity on mounting surfaces with proper alignment, achieved to within as specified.
Yes, Zintilon has rapid prototyping for the range of 5 to 25 brackets, provided in 2 to 3 weeks for fit testing and load validation. For pilot vehicles, production volumes are 100 to 1,000 brackets with first article inspection of the brackets, and annual production for commercial fuel cell vehicle programs is over 10,000 brackets with automated fabrication and statistical process control. Dimensional tolerances are verified with CMM inspection, static load tested to rated capacity with 2 to 3 times over, vibration testing at 10 to 2000 hertz with 10 to 30g acceleration, and multiple corrosion tests in salt spray per ASTM B117 for over 1000 hours.
All brackets are produced under IATF 16949:2016 attestation for automotive quality management systems. In addition, components are subjected to, and thus, comply with, the ISO 16750 automotive component environmental testing standards that include and are not limited to automotive component vibrations and shocks, severe temperature cycling between -40 to 125 degrees Celsius, and corrosion. Further compliance standards are the corrosion standards under SAE J2380 for fuel cell automotive vehicle batteries and crash safety standards under FMVSS, which state that the component must maintain structural integrity during a 50 kilometers per hour frontal impact and side impact crash. Manufacturing material certifications include dimensional inspection reports, documenting weld quality per AWS D1.1, and documenting load testing validation.
Multiple finishing options can be utilized. These options are powder coating, which can be epoxy or polyester, and get the finished product to 60 60-micron thickness or more. This can be performed to 1000+ hours of salt spray corrosion testing and beyond. E-coat cathodic electrocoating finishes to 15 microns, which is important because it provides complete coverage in recessed areas and even offers a coating for the hot-dipped galvanized zinc that attains 70 to 100 microns per ASTM A123. Anodizing Type II for aluminum also provides some of the corrosion protection and anodizing thickness of 10 to 25 microns, in addition to wear resistance. Stainless steel can be passivated per ASTM A967 to encourage a protective oxide layer to form.
Lead time is 4-6 weeks for brackets with already established designs. This includes material procurement, laser cutting, forming, welding, coating, inspection, and involves order sizes of 200 to 2,000 brackets. For custom designs that have unique geometries or need validation testing, the lead time is extended to 6-10 weeks. For rapid prototypes, lead time is 10-15 business days, which is much sooner due to expedited fabrication. Exceeding 10,000 brackets is considered high volume and requires an initial setup time of 10-14 weeks due to the establishment of tooling, welding fixtures, and the production part approval process.
We certainly do. We incorporate lightweight topology optimization which reduces mass 20-40% through finite element analysis, integrated thermal management brackets with thermal management for power electronics, modular universal brackets that fit multiple fuel cell configurations, heavy-duty brackets for commercial vehicles with load bearing requirements of 5 to 15 kn, and specialty designs such as crash-optimized brackets with controlled deformation zones, IBC compliant seismic-rated brackets for stationary systems, and marine-grade brackets with enhanced corrosion protection for maritime applications.
Precision machining maintains the flatness of the mounting surfaces within 0.010 inches. This results in optimal load distribution. Hence, avoiding stress concentration, which results in fatigue failure within a service life of 15 years, was reduced to 8. The predetermined positioning of the holes to within ±0.008 inches facilitates proper distribution of bolt preload, which is vital in eliminating loosening due to operational vibrations of 200,000 to 300,000 kilometers, also maintaining the integrity of the joint. The predetermined positioning of the holes to within ±0.008 inches facilitates proper distribution of bolt preload, which is vital in eliminating loosening due to operational vibrations of 200,000 to 300,000 kilometers, also maintaining the integrity of the joint. Predetermined positioned fuel-cell stack and proper alignment of the stacks within ±2 millimeters fuel cell stacks will obviate damage, also the performance of the membrane electrode assembly will drop within a performance range of 5 to 15 percent. Proper quality of welds will also obviate the performance range of 5 to 15 percent. Deflection of 10 to 30g vibrating joints will facilitate fuel cell assembly to the mounts. A 15-year service life representing 200,000 to 500,000 kilometers indicates proper fuel cell mounting. This is also seen in the support of stack weights from 80 to 250 kg and hydrogen tanks of 4 to 10 kg. The brackets also support 350 to 700 bar pressure with vibrating isolation of 60 to 90 percent efficiency. Proper fuel cell mounting indicates a service life of 15 years, representing 200,000 to 500,000 kilometers.
