LEAK INSPECTION METHOD

A leak inspection method includes: a gas confining step of confining a fuel gas with a predetermined pressure in a fuel gas flow field; a gas supply step of continuing to supply an oxygen-containing gas with a pressure equal to or higher than a predetermined pressure or equal to or lower than the pr...

Beschreibung
Zusammenfassung:	A leak inspection method includes: a gas confining step of confining a fuel gas with a predetermined pressure in a fuel gas flow field; a gas supply step of continuing to supply an oxygen-containing gas with a pressure equal to or higher than a predetermined pressure or equal to or lower than the predetermined pressure to an oxygen-containing gas flow field; and a measurement step of measuring the amount of pressure change per unit time of the gas confined in the gas confining step, when a switch provided to a wiring connecting an anode and a cathode without passing through an electrolyte membrane is in an OFF state.
