Dead-ended anode operation is commonly used in polymer electrolyte fuel cells, but suffers from voltage reduction with time. This study shows how a controlled anode bleed can mitigate against voltage loss and fuel dilution. Performance analysis, along with off-gas analysis, is used to characterize cell performance during dead-ended mode and an optimum bleed rate is identified to minimize voltage drop for this particular 5-cell stack.
