摘要: An electroconductive integrated substrate and a process of producing the same, which comprises a porous conductive gas diffusion layer having large number of pores with significant gas permeability, and a gas impermeable electroconductive flow field plate having landing surfaces laminated on the surface of gas diffusion layer and integrally bonded to thereto by the molten composite from the landing surface. There is provided a process for joining the gas diffusion layer to a flow field plate in an electrochemical cell. The process comprises the step of welding the landing surface of the flow field plate to the gas diffusion layer using resistance welding.

摘要: There is provided a process for sealing a coolant plate to an adjacent bi-polar plate or coolant plate in an electrochemical cell. The first coolant plate comprises at least one mating region for mating with a complementary region on the adjacent plate, the adjacent plate is a second coolant plate or a bipolar plate of the electrochemical cell, and the first coolant plate and the adjacent plate each comprise a polymer and conductive filler. The process comprises the step of welding the mating region to the complementary region to create a seal formed by the polymer at the mating region and the complementary region. Welding may be done using resistance welding or vibration welding processes.
