Abstract
Official abstract text for this publication.
A fuel cell system that includes a fuel cell that generates electricity through an electrochemical reaction between a fuel gas and an oxidant gas, and a control portion that determines whether there is leakage of the fuel gas. The control portion has start means for starting the fuel cell by raising the voltage of the fuel cell from a starting voltage to an operation voltage that is lower than an open-circuit voltage, and leakage determination means for determining whether there is leakage of the fuel gas before the voltage of the fuel cell reaches the operation voltage when the fuel cell is started.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fuel cell system comprising a fuel cell that generates electricity through an electrochemical reaction between a fuel gas and an oxidant gas; a fuel gas supply portion that supplies the fuel gas to a fuel electrode of the fuel cell; an oxidant gas supply portion that supplies the oxidant gas to an oxidant electrode of the fuel cell; and a control portion which determines whether there is leakage of the fuel gas, the control portion first charge…
