A cell stack device includes at least one cell and at least one conductive member. The cell includes an element portion. The conductive member includes a base member containing chromium, a first layer containing an oxide containing zinc, and a zinc spinel portion located at the interface between the base member and the first layer. The first layer includes a first region facing the element portion. A first overlap area ratio, at which the zinc spinel portion located at a first interface between the first region and the base member overlaps with the first interface, is less than a second overlap area ratio, at which the zinc spinel portion located at a second interface between a second region where the surface of the first layer is exposed to an oxidizing atmosphere and the base member overlaps with the second interface.

A fuel cell system includes a fuel cell that generates electricity using a fuel gas and air, an air supply that supplies air to the fuel cell, a temperature meter that measures a temperature of the fuel cell, and a controller. The controller controls the air supply to increase an amount of air to be supplied to the fuel cell in response to the temperature of the fuel cell exceeding one of a plurality of predetermined temperatures.

Fuel cell system

An electrically conductive member of the present disclosure includes a base member containing chromium (Cr), and a first layer provided on a surface of the base member and containing chromium(III) oxide (CrO). The first layer also contains titanium (Ti).
