A method of starting up at a subzero temperature a solid polymer electrolyte fuel cell stack that is formed by stacking a plurality of layers of separators and membrane electrode assemblies having a solid polymer electrolyte membrane and electrodes. The method includes a step of using a solid polymer electrolyte fuel cell stack in which the separators are made from metal and have a cross-sectional waveform structure, and a space that is formed between at least a portion of the separators and separators that are placed adjacent to this portion of the separators is used as a coolant flow passage.
Ce document décrit une méthode pour démarrer, à une température inférieure à zéro degré, une pile à combustible à polyélectrolyte solide constituée en superposant plusieurs couches formées de séparateurs et membranes-électrodes en polyélectrolyte solide. La méthode comprend une étape d'utilisation de pile à combustible à polyélectrolyte solide munie de séparateurs en métal à profil ondulé (semblable au tracé d'une onde) et présentant une cavité séparant au moins une portion de séparateurs adjacents, afin de constituer une voie de circulation pour un fluide réfrigérant.
