고분자 전해질 연료전지의 엑서지 및 열경제학적 해석

다국어 초록 (Multilingual Abstract)

Exergy and thermoeconomic analysis were performed for a 1.5-㎾ Polymer-Electrolyte Membrane Fuel Cell (PEMFC) plants which offers many advantage for cogeneration in the aspect of high electrical efficiency and low emissions. The unit costs of products of the system were evaluated by using MOPSA(Modified Productive Structure Analysis) which has been developed by the phase-change laboratory in Chung-Ang University. For full load condition, the electrical efficiency and the unit cost of electricity are about 48% and 0.091 $/㎾h respectively, which tum out to be 120% higher than the cost obtained for the 1000-㎾ gas turbine cogeneration plant, 0.076 $/㎾h. This fuel cell system may be viable economically when the initial investment cost per power is reduced to the level of the gas turbine cogeneration plant.
