Small plant components are required to deliver the reactants to the fuel cell with the required conditions. Examples of these components are blowers, compressors, pumps, and humidification systems used to deliver the gases to the fuel cell with the proper temperature, humidity, flow rate and...

One of the greatest challenges associated with PEMFCs is the water balance in the fuel cell stack. As the chemical reaction occurs in each cell, water is generated. Depending upon the load and the operating conditions, there is a tendency for the fuel cells to both flood and dry-out. The water content in the...

Fuel cell system designs range from very simple to very complex depending upon the fuel cell application and the system efficiency desired. A fuel cell system can be very efficient with just the fuel cell stack and a few other balance-of-plant components or may require many outside components to optimize...

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...
