Pressure Distribution in Bipolar Plate Flow Channels

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...

Considerations for Stainless Steel Bipolar Plate Manufacturing: Part 2

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...

Considerations for Micro and MEMs Fuel Cells

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...
