Abstract
A fuel cell device individually has an electrolyte layer which is connected, in an ion conductive manner, to the electrolyte layer of a fuel cell and a half cell formed by a single electrode and a gas chamber. An electrochemical circuit for the purpose of transferring electrolyte is provided by using the single electrode of the half cell, the electrolyte layer of the corresponding fuel cell and the half cell, and either of an oxidant gas side electrode or a fuel gas side electrode. With this circuit, quick and quantitative replenishing electrolyte can be performed.
