![]() ![]() Thus, it is a low-voltage high-current output equipment. Namely, the fuel cell lowers the output voltage but raises the output current gradually as the output power rises under the added load. Īlthough the proton exchange membrane fuel cell has the advantages mentioned above, due to its own activation loss, ohmic loss, and concentration loss, the output voltage is lowered as a result of load increase. Among them proton exchange membrane fuel cells (PEMFCs) are the most commonly used because of the following merits: (1) lower temperature during operation, accordingly leading to rapid turning on and off and rapid reaction to the load change (2) lower operation pressure, thus with higher safety (3) easily set in mode system and (4) lower emission ratio and higher conversion ratio. #Forward converter psim simulation software portableFuel cells as a source of power are usually applied to electric hybrid automobiles, distributed electric generation system, and portable and stationary power. Only water is produced after the reaction hence, there is hardly any environmental pollution. Its energy, derived from reversed reaction of electrolyzed water, produces dynamic power. The fuel cell is a clean energy without pollution. As for fuel cells, there tend to have been more and more researches and applications recently. Among many substitute energies, solar energy, wind energy, hydroelectric power, biomass energy, and fuel cells are green energies with potential development. Owing to worldwide energy crisis and awareness of environmental protection in recent years, to seek for substitute energy has become an important issue. ![]()
