Abstract
Official abstract text for this publication.
An end plate of a fuel cell stack is directly fixed to a humidifier. A resin pipe is attached to an oxygen-containing gas outlet of an end plate through a resin coupling pipe. The resin pipe includes one end having a large diameter and the other end having a small diameter. The other end is provided at an off gas supply channel of the humidifier. The off gas supply channel includes an inclined channel. The other end extends up to an end of the inclined channel where inclination of the inclined channel is started. An off gas ejection port is formed at the other end. The off gas ejection port is opened to the end of the inclined channel where inclination is started. Condensed water returned along the inclined channel flows from the off gas ejection port into the resin pipe.
First claim
Opening claim text (preview).
What is claimed is: 1. A fuel cell apparatus, that includes a humidifier coupled to a fuel cell stack, the fuel cell stack formed by stacking a plurality of power generation cells in a stacking direction, the fuel cell apparatus comprising: a reactant gas discharge passage that allows a reactant gas to flow through the reactant gas discharge passage in the stacking direction after being partially consumed in a power generation reaction, an end plate being provided at one end of…
