Resum
The performance and efficiency of an open-cathode PEM fuel cell system in dead-ended anode (DEA) configuration and hydrogen purges is analyzed in this work. Excess water and crossed-over nitrogen in the anode decrease the hydrogen concentration at the catalyst surface, which in turn causes performance losses. Purging the anode with hydrogen removes water and nitrogen and thus recovers the performance. However, this means wasting hydrogen and decreasing overall system efficiency. Gas chromatograp...
