Electricity is the most well known energy carrier. Energy from coal, crude oil, uranium, flowing water and air, etc. can be distributed to homes or businesses in the form of electricity. Similar to electricity, hydrogen has also been recognized as one potentialenergy carrier, while a hydrogen fuel cell is believed to be a viable energy conversion device due to its high performance and low negative effects [12,13]. Among the various types of fuel cells, proton exchange membrane fuel cells (PEMFCs) have achieved fast commercial development in recent years due to their inherent qualities: high efficiency, high power density, low operating temperature, fast start-up and responsiveness to load changes. At present, the PEMFChas been successfully applied in various fields such as portable power, transportation, and stationary/distributed power generation
