Hardware Information

After the membrane electrode assembly (MEA) has been fabricated, it must be integrated into a fuel cell stack. The stack has multiple jobs, including evenly distributing fuel and oxidant to the cells, collecting the current to power the desired devices, and evenly distributing or discarding heat and...

Low-temperature fuel cells have historically used CNC-machined graphite as bipolar plates. Graphite’s high-cost, high-permeability, and precise machining processes have presented difficulties for the large-scale market. Due to this, many other materials have been...

Low-temperature fuel cells have historically used CNC-machined graphite as bipolar plates. Graphite’s high-cost, high-permeability, and precise machining processes have presented difficulties for the large-scale market. Due to this, many other materials have been investigated, including carbon composite materials and...

Most people wouldn’t think that much thought needs to be put into fuel cell components such as fuel cell gaskets, spacers, and end plates, however, every part of the fuel cell stack requires careful consideration. Incorrect fuel cell gaskets and end plates can lead to gas leaks and insufficient fuel cell stack...

In fuel cells, the flow field plates are designed to provide an adequate amount of the reactants (hydrogen and oxygen) to the gas diffusion layer (GDL) and catalyst surface while minimizing pressure drop. The most popular channel configurations for PEM fuel cells are serpentine, parallel, and...

Each component of the fuel cell must be designed properly – otherwise, you run the risk of decreasing fuel cell performance. The bipolar plates are termed “bipolar” because they have flow fields on both sides. This design is very convenient when you have membrane electrode assemblies (MEAs) on both sides. In a fuel cell with a...

The design elements of a micro or MEMs fuel cell stack are the same as a larger fuel cell stack, except that there should be special considerations for...
