Fuel cell battery
Abstract
Abstract Battery is made very light, and efficient by making fuel cell units very thin and generally flat and rectangular. Cell units are stacked in facewise relation to make box like structure and electrically connected in series of working voltage. Each unit comprises fuel and oxidant electrode layers spaced by permeable insulating layer to provide electrolyte passage. Impervious, conductive barrier layer between each pair of adjacent cell units and in contact with both. In one form barrier layer has protuberances on each side contacting units to provide fuel and oxidant gas passages. Insulating layer has wettable surfaces and maintains electrolyte in contact with electrodes for high efficiency. It is about .010 inch or less thick to produce minimum ion path. Electrode layers are about .005 inch thick or less. All elements are held in tight facewise contact for compactness and also to cause all elements to provide structural support for each other.
