10W급 PEMFC의 최적운전조건에 관한 연구

Abstract

Recently energy crisis and environmental problems have been raised as the important problem for future human society. Korea has also entered activity on the alternative energy as a member of the G20.

In 1970th, alternative energy was just used on the meaning that could be substituted for fossil fuel. But alternative energy has signified as Clean Energy of Renewable Energy, New Energy, Green Energy and so on because of environmental pollution by use of fossil fuel and atomic energy after 1980. From 1997, alternative energy has been developing by Law for Promoting the Dissemination of New and Renewable Energy and it was separated into 8 Renewable Energies (Solar, Photovoltaic, Biomass, Wind Power, Small Hydro Power, Geothermy, Ocean Energy, Waste Energy) and 3 New Energies(Fuel Cell, Coal Liquefied Gas, Hydrogen Energy).

Among them, fuel cell will be the role of a new breakthrough in the field of new and renewable energy. Especially, PEMFC(Proton Exchange Membrane Fuel Cell) is most frequently used fuel cell due to its drive that can be used in low temperature condition. But it doesn't have definite drive condition of the stack. Therefore, its final price will be gone up because it can't turn out goods on a mass production basis. To compensate the defect, variety of study will be necessary.

The purpose of this study is to find out basic materials for its commercialization. As one means to this end, we had certified ideal performance curve based on ratio of stoichiometry on hydrogen and oxygen. And also, we had analyzed optimum stack drive condition on the PEMFC which has a single cell of 10W class based on the change of temperature 50, 70, 80 and 60 celsius degree.
