(JP8329994-A)      The power generation method involves constructing the positive electrode and the negative electrode, from which an electric current for power generation is to be taken, from catalytic electrodes, and interposing an electrolyte between both catalytic electrodes. A reactant is contacted with the negative catalytic electrode while heat is applied to the positive catalytic electrode and the negative catalytic electrode to form decomposition products on the negative catalytic electrode by catalytic reaction.    The method then involves reproducing the reactant on the positive catalytic electrode from the decomposition products, followed by circulating the reproduced reactant to the negative catalytic electrode to make it act on the negative catalytic electrode. The heat applied to the catalytic electrodes is solar heat.    USE/ADVANTAGE -   Clean type power generation device requiring no special heating device. Does not require reactant reproduction and release steps performed in conventional catalytic reactors.
