Accelerate hydrogen mobility with FCEV powertrain semiconductors

Hydrogen fuel-cell technology is emerging as a key enabler for zero-emission automotive transportation, complementing battery-electric vehicles where extended range and fast refueling are critical priorities. FCEV powertrain systems deliver a compelling option for long-haul trucks, medium-duty delivery vehicles, and passenger cars alike.

Infineon provides a comprehensive portfolio of power semiconductors and smart control ICs for next-generation fuel-cell powertrains. Our solutions minimize power losses and maximize system efficiency across all operating conditions, helping customers meet current and future emission regulations. At the heart of the FCEV drivetrain is the hydrogen fuel-cell stack, and Infineon's power devices and control ICs enable multi-target optimization for reduced system cost, increased power density, and modular design.

To accelerate your development, Infineon offers reference designs, demo boards, FCEV-specific software tools, layout resources, and access to design house partner contacts.

Key system characteristics of hydrogen fuel-cell EV powertrains

Hydrogen fuel-cell EV (FCEV) powertrain systems integrate multiple specialized subsystems to deliver clean, efficient, and long-range automotive propulsion.

The fuel-cell stack is the heart of the drivetrain. Hydrogen and oxygen undergo an electrochemical reaction within the stack to generate electricity that drives the traction motor, with water as the only emission. System efficiency is optimized across a wide speed range, making fuel-cell powertrains well-suited for both urban and highway operation.

Effective thermal and water management is essential to sustain stack performance and service life. Control systems precisely regulate stack temperature and moisture levels to prevent overheating and membrane degradation.

Power management components, including the fuel-cell control unit, and DC-DC boost converters regulate power distribution within the drivetrain and optimize energy flow between the fuel-cell stack and the high-voltage battery.

Infineon's semiconductor portfolio covers all these subsystems with verified reliability and performance.

Efficient fuel-cell air compressors and pumps for hydrogen drivetrains

Infineon delivers chipset solutions for efficient fuel-cell air compressors and pumps — essential subsystems for air and water management in hydrogen FCEV powertrains.

The fuel-cell air compressor delivers pressurized air to the hydrogen fuel-cell stack, enabling the oxygen extraction reaction at the cathode. Key design requirements include high efficiency across a wide speed range, compact and modular integration, low acoustic noise, contamination prevention for the fuel-cell stack, and built-in safety and diagnostic capabilities.

CoolSiC™ MOSFETs are well suited for fuel-cell air compressor drives, delivering extremely low conduction losses even at high switching frequencies. For pumps supporting powertrain management, Infineon provides dedicated motor control solutions.

For high-voltage, 24 V, and 12 V system architectures alike, Infineon’s chipset solutions cover the full range of fuel-cell compressor and pump drive configurations.

Fuel-cell control unit: ASIL-D safety for hydrogen powertrain systems

Accelerate your fuel-cell control system design with Infineon's proven semiconductor solutions — rigorously tested for automotive safety up to ASIL-D and trusted for FCEV powertrain applications worldwide.

The fuel-cell control unit (FCCU) governs all processes of the hydrogen fuel-cell system: hydrogen and air processing, thermal and water management, and safety compliance. Tight coordination between the fuel-cell controller and the powertrain domain controller is essential to meet dynamic load and thermal demands.

Infineon's AURIX™ 32-bit microcontrollers deliver functional safety up to ASIL-D with protection against manipulation and cyber attacks — ideal for automotive fuel-cell controller designs. Paired with OPTIREG™ PMICs and fuel-cell supervision ICs, AURIX™ forms a complete, safety-assured control platform extendable with OPTIGA™ TPM and F-RAM.

The new TCIx thermal conductivity gas sensor family supports hydrogen leak detection and flow monitoring, easing FCEV homologation. AURIX™ second-generation MCUs offer broad configuration flexibility across memory, peripheral, frequency, and package options — accelerating design reuse and time to market.

High-efficiency DC-DC boost converter for FCEV powertrain systems

Elevate your FCEV powertrain efficiency with Infineon's next-generation chipset solutions for fuel-cell DC-DC boost converters — designed for reliability and compact power conversion.

The fuel-cell DC-DC boost converter is a critical power stage in every FCEV drivetrain, stepping up the variable fuel-cell stack voltage to the high-voltage DC link shared by the traction inverter and high-voltage battery. This fuel-cell converter must handle a high conversion efficiency in a compact form factor.

Infineon addresses these design challenges with a broad chipset portfolio:

  • CoolSiC™ MOSFETs deliver ultra-low switching losses at high frequencies, enabling compact passive components and improved power density
  • Automotive-qualified gate driver ICs provide precise switching control, integrated protection, and diagnostics
  • High-performance AURIX™ MCUs complete the digital control loop

Our fuel-cell boost converter solutions support flexible unidirectional and bidirectional topologies, automotive qualification with integrated isolation, and evaluation kits for fast prototyping — the right solution for your DC-DC converter requirements.
