Filed:

Apr 5, 2001

Appl. No.:

09/827368

Inventors:

Anthony B. LaConti - Lynnfield MA
William A. Titterington - River Ranch FL
Larry L. Swette - Newton MA
Ricardo Leon - Braintree MA

Assignee:

Giner Electrochemical Systems, LLC - Newton MA

International Classification:

C25B 900

US Classification:

204263, 204252, 204253, 204266, 429 32, 429 34, 429 35, 429 38

Abstract:

Electrochemical cell comprises, in one embodiment, a proton exchange membrane (PEM), an anode positioned along one face of the PEM, and a cathode positioned along the other face of the PEM. To enhance electrolysis, platinum catalysts are present between the anode and the PEM and between the cathode and the PEM. A multi-layer metal screen for defining a first fluid cavity is placed in contact with the outer face of the anode, and an electrically-conductive, spring-like, porous pad for defining a second fluid cavity is placed in contact with the outer face of the cathode. The porous pad comprises a mat of carbon fibers having a density of about 0. 2-0. 55 g/cm. Cell frames are placed in peripheral contact with the metal screen and the compression pad for peripherally containing fluids present therewithin. Electrically-conductive separators are placed in contact with the metal screen and the compression pad for axially containing fluids present therewithin. A plurality of the cells may be arranged in series in a bipolar configuration, without requiring a separate compression pad between cells (for differential pressures up to about 400 psi).

Abstract:

Electrolysis cell comprises, in one embodiment, a proton exchange membrane (PEM), an anode positioned along one face of the PEM, and a cathode positioned along the other face of the PEM. A multi-layer metal screen for defining a first fluid cavity is placed in contact with the outer face of the anode, and an electrically-conductive, compressible, spring-like, porous pad for defining a second fluid cavity is placed in contact with the outer face of the cathode. The porous pad comprises a mat of carbon fibers bound together with one or more, preferably thermoplastic, resins, the mat having a density of about 0. 2–1. 5 g/cm. Cell frames are placed in peripheral contact with the metal screen and the compression pad for peripherally containing fluids present therewithin. Electrically-conductive separators are placed in contact with the metal screen and the compression pad for axially containing fluids present therewithin. A plurality of the cells may be arranged in series in a bipolar configuration without requiring a separate compression pad between cells (for gas pressure differentials up to about 400 psi or greater).
