Abstract
Abstract A solid polymer electrolyte cell includes a solid polymer electrolyte membrane, an anode disposed on one side of and in contact with the membrane wherein the anode includes a substrate coated with lead dioxide and formed with one or more grooves therein, a cathode including a body of sintered nickel disposed on the other side of and in contact with the membrane, and a support structure corrugated on a surface portion thereof with such surface portion being in contact with the body of sintered nickel to maintain the body in contact with the membrane. With this construction, water may be supplied to the grooves in the anode to ultimately cause a reaction at the interface of the membrane and the cathode to product hydrogen gas.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
89 words
A solid polymer electrolyte cell comprising a solid polymer electrolyte membrane, an anode disposed on one side of and in contact with said membrane, said anode including a substrate coated with lead dioxide and being formed to enable the flow of fluid between the anode and membrane, with the lead dioxide being maintained in contact with the membrane, and a cathode formed of a body of sintered material adapted to enable the flow of fluid therethrough and disposed on the other side of and in contact with said membrane.
Claim 2
Dependent Claim
89 words
A solid polymer electrolyte cell comprising a solid polymer electrolyte membrane, an anode disposed on one side of and in contact with said membrane, said anode including a substrate coated with lead dioxide and being formed to enable the flow of fluid between the anode and membrane, with the lead dioxide being maintained in contact with the membrane, and a cathode formed of a body of sintered material adapted to enable the flow of fluid therethrough and disposed on the other side of and in contact with said membrane.
Claim 3
Dependent Claim
17 words
A cell as in claim 1 wherein said body of sintered material is laminated onto said membrane.
Claim 4
Dependent Claim
45 words
A cell as in claim 1 further comprising a support structure disposed in contact with said body of sintered material to maintain the body in contact with the membrane, the surface area of the support structure which is in contact with said body being corrugated.
Claim 5
Dependent Claim
38 words
A cell as in claim 1 wherein said anode is formed with one or more grooves therein facing the membrane, the grooved bottoms being spaced from the membrane to thereby enable the conveyance of fluid through the grooves.
Claim 6
Dependent Claim
17 words
A cell as in claim 1 wherein said cathode is comprised of a body of sintered nickel.
Claim 7
Dependent Claim
13 words
A cell as in claim 1 wherein said substrate is composed of graphite.
Claim 8
Dependent Claim
14 words
A cell as in claim 1 wherein said membrane is a perfluorosulfonic acid membrane.
Claim 9
Dependent Claim
47 words
A cell as in claim 1 further comprising means for applying water to the grooves in the anode to flow therethrough means for applying a D.C. current to the cathode and anode, and means for collecting the products produced at the interface of the membrane and cathode.
