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.

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.
摘要翻译：燃料电池10的拆卸处理向燃料气体导管6g和氧化气体导管7g两者供给流体。由于各气体导管6g，7g的出口被屏蔽，所以各气体导管6g，7g的内压或通路压力逐渐上升，最终超过燃料电池10的发电特定的通过压力水平。高通道压力使膜电极组件（MEA）2的气体扩散电极4b和限定燃料气体导管6g的隔板6沿相反方向膨胀，以使气体扩散电极4b和隔板类似地，高通道压力使MEA2的气体扩散电极5b和限定氧化气体导管7g的隔板7以相反的方向膨胀，以在气体扩散电极5b和隔板7之间形成间隙。所供应的流体然后通过这些间隙流出分离器6和7与MEA2之间的密封件。这些流动提高通道内压力并释放密封件。
