A Review on Proton Exchange Membrane Fuel Cell Applications & Challenges

For unpolluted and effective power generation, proton exchange membrane fuel cells are reflected to be a positive technology. This interest is due to their high efficiency, high power density and no environmental pollution. Polymer electrolyte membrane fuel cells (PEMFC) are the foremost appropriate form of fuel cells to be used in vehicles due to their low performance temperature and high power density. Proton exchange membrane is that the key component of electric cell system. But there are various challenges remaining that need to be overcome previously PEMFCs can effectively and economically substitute for the traditional energy systems. During the last few decades some, numerous efforts are made to advance the PEM cell technology and fundamental research. Factors like safe storage of hydrogen, durability and price still remain because the major barriers to fuel cell commercialization and so are the most important concern among scientists.
