Abstract:
1. An apparatus for pre-activating a polymer electrolyte fuel cell, which supplies water vapor while hot pressing a unit cell stack with gas diffusion layers stacked on both sides of a membrane electrode assembly comprising a polymer electrolyte membrane provided between two electrode catalyst layers to fix the gas diffusion layers arranged on both sides of the membrane electrode assembly and perform pre-activation at the same time, wherein the apparatus comprises a first plate and a second plate hot pressing the unit cell stack, each having a flow channel supplying water vapor to opposing inner surfaces with the unit cell stack therebetween and comprising a resistor producing heat in response to an electrical signal; a compressor connected to the first plate or the second plate and applying a pressure to the first plate or the second plate; a temperature controller connected to the resistors and controlling the temperature of the first plate and the second plate; and a water vapor supplier connected to the flow channels of the first plate and the second plate and supplying water vapor.
