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) 1 includes an electrochemical device (fuel cell) 2 which has an electrolyte membrane 6 clamped between opposed electrodes 5 and 7 and which generates electrochemical energy by a reaction of an alcohol with water at one (fuel electrode) 5 of the electrodes 5, 7 , and a fuel evaporating section 11 by which a fuel including said alcohol and substantially not containing water is supplied in a gaseous state to the side of the one 5 of the electrodes 5, 7 of the electrochemical device 5 . The method of driving the electrochemical energy generating apparatus 1 includes supplying the fuel in the gaseous state to the one 5 of the electrodes 5, 7 by the fuel evaporating section 11.
