Abstract
A water detection device is provided for a power generation cell. The power generation cell has a reactant gas flow field (oxygen-containing gas flow field) configured to allow a reactant gas to flow along a membrane electrode assembly. The water detection device includes an electrically conductive member and a support member. The support member is an insulating member. The support member covers, and supports an electrically conductive member, and has an opening which exposes part of the electrically conductive member as an electrode. The opening is provided at a position facing a reactant gas flow field.
