Abstract:
1. A passive fuel cell assembly, comprising: a membrane electrode assembly; an anode current collector; a cathode current collector, wherein the anode current collector and the cathode current collector are disposed at two opposite sides of the membrane electrode assembly; a hydrophilic and gas-impermeable layer disposed on the anode current collector; a water absorbent and gas-permeable layer disposed between the anode current collector and the hydrophilic and gas-impermeable layer; and a gas-liquid separation layer disposed on the hydrophilic and gas-impermeable layer such that the hydrophilic and gas-impermeable layer is disposed between the gas-liquid separation layer and the anode current collector, wherein the hydrophilic and gas-impermeable layer contacts with the gas-liquid separation layer, and there is no air gap between the hydrophilic and gas-impermeable layer and the gas-liquid separation layer.
