Fuel-Cell Electric Air Compressor
High efficiency and reliability with Infineon fuel-cell air compressors for electric vehicle applications
At Infineon, we understand the role that fuel-cell electric vehicle technology can play in the reduction of global CO2 emissions. However, to ensure the success of fuel-cell vehicle adoption in the mass market, fuel-cell technology must first be made readily available to the average consumer in the form of widespread refueling stations and low vehicle ownership costs. Infineon offers a range of semiconductor solutions for the easy and cost-effective manufacture and design of electric vehicle subsystems, including fuel-cell electric air compressors.
Infineon’s components for fuel-cell air compressors are designed for optimum efficiency and performance when it comes to the integration into electric vehicle drivetrain systems. Some of the greatest challenges facing designers, including achieving the highest possible system efficiency and dynamics over a wide air flow rate and compressor speed range, all while keeping costs low. At the same time, systems should be both compact and modular, run as quietly as possible, and meet the necessary safety and diagnostic requirements. It’s also important that the fuel-cell stack is protected from contamination at all times.
Infineon’s portfolio of products is specially designed to help you overcome these design barriers with ease.
Fuel-Cell Air Compressors
Fuel-cell air compressors in electric vehicle propulsion systems are responsible for forcing air into the fuel cell stack, where it is used as an oxidant to produce a reaction with hydrogen ions and electrons at the fuel cell cathode to form water.
Air compressor systems are important for controlling air mass flow rate and air pressure. Infineon’s portfolio of CoolSiC™ MOSFET products are particularly suitable for air compressor systems, due to their very low, temperature-independent conducting losses, even at high switching frequencies. Our next-generation Silicon Carbide (SiC) Power MOSFET technology offers designers an even higher degree of flexibility to enable increased efficiency and reliability in fuel-cell air compressor systems.
