The H2/CO2 ratio of reformate depends on its primary fuel as well as the type of reforming process. When reformate is used as fuel for a polymer electrolyte fuel cell (PEFC), its H2/CO2 ratio affects the performance of the cell as well as the water management condition of polymer electrolyte membrane. Cell voltage of 50 cm2 PEFC was measured with simulated reformate gases of different H2/CO2 ratios and examined in connection with water management condition of the membrane. The result indicates that precise water management is required when PEFC operates with a fuel of high CO2 content.
