Embodiment Construction

[0038] The illustrated fuel cell cell is designated 10 and includes a housing 12 including two elongated side walls 14 , two narrow end walls 16 and a base 18 . The vertical groove 20 extends over the full height of the inner face of each end wall 16 . The top cover 22 of the housing 12 has four slots 24 and three sets of holes 26 , 28 and 30 alternating with the slots 24 . The groove 20 in the end wall 16 continues across the upper surface of the base 16 and the underside of the top cover 22 . The groove in the upper surface of the top cover is indicated at 32 .

[0039] Reference numeral 34 designates an electrode assembly of the fuel cell. Assembly 34 includes a substrate 36 that is porous to allow electrolyte in housing 12 to permeate from one side to the other. Substrate 36 is a material such as polyethylene so that it acts as an electrical insulator. The base plate is formed with four tabs 38 , 40 , 42 and 44 protruding upward.

Abstract

A fuel cell is disclosed which comprises a casing (12) and an electrode assembly in the casing. The electrode assembly comprises a porous substrate (36) and first and second electrodes (46, 48) on one side of the substrate. Third and fourth electrodes (60, 62) are provided on the other side of the substrate. Each electrode includes a tab (36, 38, 42, and 44) by means of which an electrical connection can be made to that electrode. There is electrolyte in the casing.

Description

technical field [0001] The present invention relates to a hybrid structure that can be used as a fuel cell cell and a hydrogen generator, and which can also be used as a battery. Background technique [0002] Fuel cells have been of interest for more than 150 years as potentially more efficient and less polluting means of converting hydrogen and carbonaceous or fossil fuels to electricity than conventional heat engines. Research into the use of fuel cell cells to generate utility power and drive electric vehicles has been going on for quite some time, but progress has been slow. Recent developments in fuel cell technology have renewed interest in such cells for these and new applications. [0003] When the terminals of a conventional fuel cell cell are connected to an external power source, the fuel cell cell releases hydrogen and oxygen. Such cells may be operated in reverse to provide them with hydrogen and oxygen (which may be oxygen in atmospheric air). It then genera...
