FUEL CELL STACKS

The core innovative fuel cell technology developed and patented by EHG is based on two main approaches to achieving genuine scalability of fuel cell production:

  • A uniquely simplified and re-designed fuel cell stack at the micro level, which making it more compact, lightweight and efficient (1st generation cell pitch <0.9 [mm]).

  • A completely new approach and concept of fuel cell stack design and assembly with high micro precision that eliminates the conventional method of stack assembly. 

Our product offering can be used in stationary applications such as commercial and residential buildings, data centres, telecom towers, hospitals, etc. Furthermore, due to its compactness, our technology will be a front-running candidate for mobile/automotive applications (buses, trucks, forklifts, boats, drones, etc.) where weight and volume reduction are two key criteria.

Two stacks with different active areas are available:

  • Mini-Stack for small applications up to +3 [kW];

  • Large-Stack for large application up to +100 [kW];

  • Liquid cooled stacks - recommended maximum dT across the stack <10 [°C]

  • Low pressure drop across the stack <25 [kPa]

  • Fuel supply: either pure hydrogen or reformate gas

  • MEA customised by EHG - can be assembled with MEA from various suppliers

  • Gas connectors: either standard fittings or customised

  • Flexible CVM connection

For future technical information please contact us (Here).

We have in-depth knowledge and expertise in the areas of low and high temperature fuel cells and have worked with a range of technologies and concepts.  This includes the design and development of CHP or hybrid systems, and the integration of fuel cells with other technologies.

We can assist you to design your own stack - read more about our approach (Click here).

What is a Fuel Cell?

Fuel cells are devices that converts the chemical energy of a fuel (usually hydrogen) into electricity with an electrochemical reaction. It is typically comprised of an electrolyte, porous electrodes, fuel and oxidant supply channels and current collectors. The figure on the right is a schematic representation of Polymer Electrolyte Membrane Fuel Cell (PEMFC) and Solid Oxide Fuel Cell (SOFC) fuel cells with electrodes and electrolyte identified.
