Abstract
An oxidation gas discharging structure is applied to a fuel cell stack that includes an end plate arranged on an end of a fuel cell body. The oxidation gas inside the fuel cell body is discharged to the outside through a through hole extending through the end plate. A slope is formed on the bottom face of the through hole to rise toward the downstream side. The slope restricts condensed water from moving downstream.
