However, it is difficult for any new technology to quickly achieve the economical feasibility of energy production [8–10]. Many researchers have suggested that better energy conversion methods and improvements in conversion efficiency should be effective ways to deal with energy utilization. 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
