[ What is claimed is:] [1.]1. An electrode structure comprising: a current collector sheet, a first electrode layer, and a second electrode layer; said first electrode layer being between said current collector sheet and said second electrode layer; said first layer comprising a first group of carbon particles and said second layer comprising a second group of carbon particles; said first layer being uncatalyzed or catalyzed with a first group of very finely divided catalytic particles; and said second layer being catalyzed with a second group of very finely divided catalytic particles; provided that the weight ratio of catalytic particles to carbon particles of the first layer is less than that of the second layer.
