ABSTRACT:
An electrochemical energy generating apparatus with which the crossover of a fuel can be suppressed and a method of driving the apparatus are disclosed. The electrochemical energy generating apparatus (e.g., a fuel cell system) includes an electrochemical device (fuel cell) which has an electrolyte membrane6clamped between opposed electrodes and which generates electrochemical energy by a reaction of an alcohol with water at one (fuel electrode) of the electrodes and a fuel evaporating section by which a fuel including said alcohol and substantially not containing water is supplied in a gaseous state to the side of the one of the electrodes of the electrochemical device. The method of driving the electrochemical energy generating apparatus1includes supplying the fuel in the gaseous state to the one of the electrodes by the fuel evaporating section.
