Abstract
Abstract An improved electrode comprising a mixture of a metal and a metal salt incorporated into a matrix material. This basic electrode material is coatable on an electrically conducting substrate to provide an excellent quality, low cost electrode assembly. The method of making the same comprising forming a mixture of a metal and metal salt incorporating the resultant mixture into a matrix therefor and applying that resulting mixture to the electrically conducting substrate.

Claim 1
Independent Claim
64 words
In an electrode component for electrochemicaL use the combination of an electrically conducting substrate and a mixture of a powdered metal and powdered salt of the metal, a matrix material, said mixture being contained within the matrix material, said matrixed mixture constituting a non-pressed coating over said electrically conducting substrate, said matrix material comprising a mixture of a hydrophobic polymer and a hydrophilic polymer.
Claim 2
Dependent Claim
116 words
In an electrode component for electrochemical use the combination of an electrically conducting substrate and a first mixture of a powdered metal and a powdered salt of the metal, a first matrix material, said first mixture being contained within the first matrix material to form a first matrixed mixture constituting a first coating over said electrically conducting substrate, a second mixture of a powdered metal and a powdered salt of the metal, a second matrix material, said second mixture being contained within the second matrix material to form a second matrixed mixture constituting a second coating over the first coating, said first matrix material comprising ahydrophobic polymer and said second matrix material comprising a hydrophilic polymer.
Claim 3
Dependent Claim
