Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
120 words
An improved electrode assembly comprising a. an anodic base plate comprising a layer of titanium, b. a cathodic base plate comprising a layer of iron or steel, c. a plurality of titanium anodes extending outwardly from the anodic base plate, d. a plurality of cathodes of iron or steel extending outwardly from the cathodic base plate, e. a layer consisting of silver interposed between said anodic base plate and said cathodic base plate, f. the layers set forth in (a), (b), and (e) being joined together in a laminate so that the silver layer forms a H 2 -impermeable barrier between the anodic base plate and the cathodic base plate, the active titanium surface being coated with a conductive metal.
Claim 2
Dependent Claim
