摘要： A process of disassembling a fuel cell 10 supplies a fluid to both a fuel gas conduit 6g and an oxidizing gas conduit 7g. Since outlets of the respective gas conduits 6g and 7g are shielded, the internal pressure or in-passage pressure of the respective gas conduits 6g and 7g gradually rises and eventually exceeds a specific in-passage pressure level for power generation of the fuel cell 10. The high in-passage pressure expands a gas diffusion electrode 4b of a membrane electrode assembly (MEA) 2 and a separator 6, which define the fuel gas conduit 6g, in opposite directions to make a clearance between the gas diffusion electrode 4b and the separator 6. Similarly the high in-passage pressure expands a gas diffusion electrode 5b of the MEA 2 and a separator 7, which define the oxidizing gas conduit 7g, in opposite directions to make a clearance between the gas diffusion electrode 5b and the separator 7. The supplied fluid then flows out through these clearances into seals between the separators 6 and 7 and the MEA 2. These flows raise the in-passage pressure and release the seals.

摘要： A fuel cell stack comprises a stack of three or more fuel cells, each having an assembly in which an anode electrode and a cathode electrode are respectively joined to either side of an electrolytic membrane. The anode electrode is provided nearer to one end, in the stack direction of the fuel cell, than the cathode electrode. Temperature regulating parts for regulating the temperature of the anode electrode of one fuel cell of any two adjacent fuel cells and the cathode electrode of the other fuel cell are disposed at a plurality of positions arranged in the stack direction. The provided temperature regulating parts perform temperature regulation so that the heat dissipating capability of the anode electrode is different in the stack direction from that of the cathode electrode.

摘要： Respective heaters 21 through 24 receive power supply and start heating. The heaters 21 through 24 keep heating sealing layers 8 to or over a softening temperature at which the sealing layers 8 are softened or molten. After the sealing layers 8 are softened or molten to weaken the adhesive force between a pair of separators 6 and 7, the heaters 21 through 24 are detached from a fuel cell 10. The worker then completely separates the pair of separators 6 and 7 from each other with some tool or by hand and removes an MEA 2 from the fuel cell 10.
