Abstract
Abstract The introduction of one or more ingredients of a chemical reaction into a foam atmosphere for the purpose of promoting such reaction. With respect to the application of the present invention to fuel cells, the electrolyte in one or both the anode and cathode cabinets of a fuel cell is modified with the addition of a foaming agent so that the electrodes of the cell are in contact with foamed electrolyte.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
16 words
The method of claim 1 wherein said anode and cathode are only in said foam layer.
Claim 2
Dependent Claim
11 words
The method of claim 2 wherein said fuel is a gas.
Claim 3
Dependent Claim
11 words
The method of claim 3 wherein said oxidant is a gas.
Claim 4
Dependent Claim
41 words
The method of claim 4 wherein said gases quickly saturate the walls of the foam electrolyte bubbles, with the bubbles breaking to run down over the electrode and provide, on a continuous basis, freshly saturated fuel or oxidant to the electrode.
Claim 5
Independent Claim
76 words
A method of promoting an electrochemical reaction involving one or more reactants, said electrochemical reaction being carried out through the presence of an anode compartment and a cathode compartment, said method comprising adding a foaming agent to the reactants, agitating said reactants to create a layer of foam containing said reactants, positioning an anode and a cathode at least partially in said foam so that said electrochemical reaction is promoted by the presence of said foam.
Claim 6
Dependent Claim
62 words
In a fuel cell comprising an anode compartment and a cathode compartment, an electrolyte for said anode and cathode compartments, means to deliver fuel to said anode compartment and oxidant to said cathode compartment, the improvement comprising providing a portion of said electrolyte as a layer of foam containing fuel and positioning an anode and cathode substantially only in said foam layer.
Claim 7
Dependent Claim
17 words
The fuel cell of claim 7 wherein said anode and cathode are only in said foam layer.
Claim 8
Dependent Claim
12 words
The fuel cell of claim 8 wherein said fuel is a gas.
Claim 9
Dependent Claim
12 words
The fuel cell of claim 9 wherein said oxidant is a gas.
