Abstract
Official abstract text for this publication.
A method of starting operation of a fuel cell stack includes the steps of performing gas replacement by supplying a fuel gas to a fuel gas flow field from a downstream side of the fuel gas flow field through a fuel gas discharge passage, and supplying an oxygen-containing gas to an oxygen-containing gas flow field from an upstream side of the oxygen-containing gas flow field through an oxygen-containing gas supply passage. After the step of performing gas replacement, normal power generation is carried out by supplying the fuel gas to the fuel gas flow field from an upstream side of the fuel gas flow field through a fuel gas supply passage, and supplying the oxygen-containing gas to the oxygen-containing gas flow field from the upstream side of the oxygen-containing gas flow field through the oxygen-containing gas supply passage.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of starting operation of a solid polymer electrolyte fuel cell for generating electrical energy by electrochemical reactions taking place between an oxygen-containing gas and a fuel gas, the solid polymer electrolyte fuel cell being formed by stacking a membrane electrode assembly and separators, the membrane electrode assembly including a cathode and an anode as a pair of electrodes, and an electrolyte interposed between the cathode and the anode, t…
