이중구조 촉매층으로 구성된 MEA의 성능 평가
Performance Evaluation on MEA with Double Layered Catalyst
- 발행 : 2006.06.22
초록
An experimental study is performed to evaluate the performance and the efficiency by humidifying MEA and by making the double-layered catalyst in a fuel cell system which is taken into account the physical and thermal concept. An electrical output produced by PEMFC(Polymer Exchange Membrane Fuel Cell) is measured to assess the performance of the stack and the efficiency is also evaluated according to the different situation in which is placed with and without the humidification of MEA(Membrane Electrolyte Assembly). Subsequently, It is found that the measured values of MEA voltage and current are influenced by the MEA temperature, humidification, and the double-layered catalyst which gives more enhanced values to apply for electric units.
