Fueling the change

Our fuel cell portfolio includes hydrogen proton exchange membrane fuel cells (PEMFCs) for both mobility and stationary applications and solid oxide fuel cells (SOFCs) for stationary power supply. Without sacrificing power or performance, our fuel cell systems generate electricity through a chemical reaction. When hydrogen fuel mixes with atmospheric oxygen as it passes through a fuel cell stack, producing zero-emissions electricity to power a motor. Water and heat are the only by-product of hydrogen fuel cell power.

Building emissions-free power

  • Fuel cells are at the heart of a fuel cell power module. The smallest component, they are the individual cells that convert fuel into electricity without combustion.

    Individual Fuel Cells

  • Fuel cells can be combined in any quantity to form a fuel cell stack. These stacks are placed in fuel cell power modules to provide scalable power to fit an application’s unique energy needs.

    Fuel Cell Stacks

  • Fuel cell stacks are contained within a larger system - a module - that includes fuel, water and air management, coolant control, hardware, and software. The systems vary in size and use according to their different applications, from transportation to industrial machinery to backup power that can supplement the electric grid.

    Advantages of fuel cell technology 

    Fuel cells can be integrated into a wide range of applications and provide sustainable power advantages across multiple sectors, including transportation and power grids.

    Decarbonized power
    When fueled with hydrogen generated from renewable energy, such as solar, wind or hydropower, fuel cells produce zero tailpipe emissions.

    Free of NOx emissions
    All internal combustion engines (ICE), even the most fuel efficient, emit nitrous oxide related to the combustion process. Combustion does not occur in a hydrogen fuel cell power module, thus produces no NOx emissions.

    Higher energy efficiency
    Because they convert chemical potential energy directly into electricity, fuel cells avoid thermal bottlenecks as the process is more efficient without the need to further process and convert stored energy. 

    Fast, familiar fueling
    Refueling a fuel cell power module with hydrogen is similar to refueling a diesel engine vehicle. Instead of a diesel pump, a hydrogen pump is used to ‘fill up’ the hydrogen fuel tank.


    Better for the environment
    With water and steam being the only byproduct, PEM fuel cells won’t pollute the air with emissions.

    Reduced maintenance 
    Fuel cells have fewer moving parts that are necessary to keep running at optimal performance compared to traditional combustion engines. Less parts needing upkeep = less overall maintenance required.

    • Solid oxide fuel cells

      SOFCs are suitable for a variety of industries that need to generate on-site power to achieve greater energy resiliency and lower emissions. They are more efficient compared to traditional energy production sources and offer greater flexibility in the type of fuel that can be used to produce energy.
