Abstract:
1. A fuel cell disassembly method of disassembling a fuel cell, the fuel cell comprising: an electrode assembly having an electrolyte interposed between a pair of electrodes; sealing layers located to surround a periphery of the electrode assembly; and a pair of separators arranged across the electrode assembly and bonded to the sealing layers, where one of the separators facing one of the electrodes has a fuel gas conduit, while the other of the separators facing the other of the electrodes has an oxidizing gas conduit, said fuel cell disassembly method comprising the step of: supplying a specific fluid (which is referred to as a fluid supply for disassembly of the fuel cell) to at least one of the oxidizing gas conduit and the fuel gas conduit to facilitate separation of the electrode assembly from the pair of separators, wherein the fluid supply for disassembly of the fuel cell comprise one of more members selected from the group consisting of one or more organic solvents and water, wherein the specific fluid is supplied to heighten an in-passage pressure of at least one of the oxidizing gas conduit and the fuel gas conduit over a level of in-passage pressure level during power generation by the fuel cell, and wherein the specific fluid has a function of lowering an adhesive force of the sealing layers.
