摘要: Abstract In this study, the combination of a gas diffusion layer (GDL) with wettability distribution and gas-flow channels microgrooves is proposed to reduce concentration overvoltage polymer electrolyte fuel cells. The effects wettability-distribution pattern linear angle stripe-wise GDL on cell performance are experimentally investigated. Examination show that not only liquid-water inside hybrid but also control surface important factors consider in reducing overvoltage. Furthermore, considering effect, when channel shallow, especially at 20°, critical current maximum power maximized.
