摘要:
A subassembly for a stack of electrochemical cells that includes a porous metal sheet having a first face and a second face with a hydrophobic, carbonaceous gas diffusion layer disposed within the pores along the first face of the porous metal sheet. The second face of the porous metal sheet defines a flow field while that portion of the porous metal sheet filled with the gas diffusion layer forms a current collector. The subassembly may further include a metal gas barrier metallurgically bonded to the second face of the porous metal sheet to act as a gas barrier between the porous metal sheet and a second porous metal sheet having a second gas diffusion layer disposed within the pores along a face of the second porous metal sheet. Preferably, the gas diffusion layers are applied as a paste to the porous metal sheet and then dried.
