Abstract

When reformer for fuel cel is used, CO in hydrogen gas leads to a seriously decreased membrane elec-trode assembly (MEA) performance by catalyst poisoning. The effect of CO on performance of modified MEA bysputtering method is studied in this paper. The experimental results show that sputtered Pt and Ru thin film improvea single cell performance of MEA and sputtered metal thinanode show improved CO tolerance test result. Moreover, Pt, Ru and PtRu thin film by sputtering had influenceon the CO tolerance with air injection proces.
