Proton-exchange membrane (PEM) fuel cells are being developed for both automotive (motive and/or auxiliary) and stationary (residential) power applications. Solid oxide fuel cells (SOFCs) also are being pursued for a number of power generation applications, including stationary (residential and utility), and automotive (auxiliary) power sources. For both of these types of fuel cells, the use of...

Polymer electrolyte membrane fuel cells (PEMFCs) are considered an eco-friendly, highly efficient, and pollution-free alternative energy source. Due to their outstanding properties, these used in stationary transport applications like wild areas, military, space missions, the auto sector, a few others. Therefore properties refer PEM as future In this work, serpentine has been analyzed under dif...

PEMFCs depend on proper water management to obtain high power density and energy efficiency. Traditionally, water management has been addressed by system design and engineering. That is, by adding auxiliary systems to the basic fuel cell system to provide humidification to the anode and remove water from the cathode. This approach adds significant complexities and costs and reduces the overall ...
