PEMFC cells work at by and large low temperatures (underneath 100 degrees Celsius) and can tailor electrical respect meet dynamic power necessities. On account of the by and large low temperatures and the usage of significant metal-based anodes, these cells must work on unadulterated hydrogen. PEMFC cells are at the present time the fundamental advancement for light commitment vehicles and materials dealing with vehicles, and to a lesser degree for stationary and distinctive applications. The PEMFC vitality unit is in like manner sometimes called a polymer electrolyte layer control gadget Hydrogen fuel is set up at the anode where electrons are detached from protons on the surface of a platinum-based force. The protons experience the layer to the cathode side of the cell while the electrons go in an outside circuit, delivering the electrical yield of the...

A commercial software „Fluent ‟ is used for computation. The mass transfer process with electrochemical reactions is coupled and solved using self-written user defined functions. The model is used to investigate the effect of Microporous layer (MPL) thickness on methanol crossover and cell performance. The performance of the cell is computed for different microporous layer. The model results show that the methanol crossover decreases with increasing MPL thickness. It is observed that the methanol crossover is reduced without affecting the cell performance at low current density and fuel utilization efficiency is enhanced due to decrease in fuel loss.
