Four different types of inlet flow headers are considered and the flow patterns according to the air inlet flow header configuration are numerically obtained. The computed result for a modified header predicts about 8.5% improvement in the air flow distribution at 10-cell cathode channel inlets. Experiments are also carried out to confirm the numerical findings by measuring actual air flow distributions and the polarization curves of the PEMFC stack. 대한설비공학회 공기측 입구헤더의 형상 개선을 통한고분자 전해질 연료전지의 성능 향상 Performance Enhancement of a PEMFC byModification of Air Inlet Flow Header Configuration Article 2 설비공학 논문집, v.19, no.4, pp.339 - 345 설비공학 논문집 19 4 339 345 kci ART001043742 Air flow rate(공기유량) CFD(전산유체역학) PEMFC(고분자전해질 연료전지) Polarization curve(성능곡선)
