摘要： Provided are an electrode to enhance the power generation efficiency in a fuel cell, in particular a single-chamber solid electrolyte fuel cell, and such an electrode. The electrode of the present invention comprises ΔEh, represented by the following formula (1), being not less than −10 mV and not more than 100 mV. ΔEh=E0−E3  (1) (where E0 denotes an electrode potential when a gas having a hydrogen concentration of 0% (an oxidizing gas only) makes contact with the electrode at room temperature, and E3 denotes an electrode potential when a mixed gas having a hydrogen concentration of 3 volume % (a hydrogen gas and the oxidizing gas) makes contact with the electrode at room temperature.)
