HEAT PRESSING APPARATUS FOR PRE-ACTIVATING POLYMER ELECTROLYTE FUEL CELL

摘要

The present invention relates to a hot-compression apparatus with a function of pre-activating a polyelectrolyte fuel cell. More specifically, in terms of manufacturing a diffusion layer assembly by laminating a gas diffusion layer onto an electrode catalytic layer formed on the top and bottom surfaces of an electrolyte membrane respectively and then hot-compressing the same thereafter, the present invention relates to a hot-compression apparatus, which pre-activates a polyelectrolyte fuel cell functioning in carrying out an activation process and a leakage inspection of the electrolyte membrane in the course of a hot-compression process, Therefore, the hot-compression apparatus inspects leakage on the electrolyte membrane by creating pressure difference by applying pressure, between the top and bottom surfaces of a laminate, with nitrogen and then pre-activates the polyelectrolyte fuel cells by applying pressure with steam onto the top and bottom surfaces of the laminate.
