摘要： A sub-stack assembly 100 of a number of cells 102 bonded together with thermoplastic film 104 is disclosed. Each of the individual cell components are bonded to one another with thermoplastic film 104. A number of sub-stack assemblies 100 are stacked and sealed relative to one another by a soft compliant gasket seal 106, such as a foam rubber or other suitable materials. As a result, only one soft foam rubber seal 106 would be required for each sub-stack assembly 100 rather than for every cell.

摘要： An improved membrane electrode assembly for PEM fuel cells is provided. Catalyst layers (40, 44) are disposed, respectively, on both sides of the proton exchange membrane (48). Gas diffusion layers (38, 50) are disposed, respectively, on sides of the catalyst layers (40, 44) not in contact with the proton exchange membrane (48). Porous substrates (32, 34) are disposed, respectively, on sides of the gas diffusion layers (38, 50) not in contact with the catalyst layers (40, 44). The porous substrates (32, 34) are impregnated at their periphery with a thermoplastic material. Thermoplastic film layers (42, 46, 68) are employed at the periphery of the assembly (10) between component parts to bond and seal water transport plates (12' and 16) to each other, as well as substrates (32, 32', 34) to the membrane electrode assembly (20). A foam tape 60, 62, 62' are employed to seal water transport plates (12, 12', 16) to respective substrates (32, 32', 34).

摘要： A seal structure 60 for a porous plate of an electrochemical cell, such as plates 18, 20, includes a sealing material disposed in a seal region 66 of the plate to form a hydrophilic barrier to gas with an electrolyte and a hydrophobic layer 62 to block the loss of electrolyte from the hydrophilic layer is disclosed. Various construction details including a method for making the plate are disclosed which increase the cross pressure the sealing region of the plate can withstand. In one embodiment, the seal region 66 is impregnated with powder having a low structure and predetermined particle size using a pressurized liquid carrier. A FEP Teflon film bonds adjacent electrolyte reservoir plates together.
