Abstract A fuel cell wherein an electrically insulating annular holder of natural or synthetic rubber comprises inwardly extending collars provided with sealing lips which engage marginal portions of disk-shaped oxygen and fuel electrodes which define between themselves oxygen and fuel chambers. The oxygen chamber receives oxygen and discharges residues through partly radial and partly axially parallel inlets and outlets of the holder. Similar inlets and outlets are provided in the holder for admission of fuel and electrolyte into and for evacuation of combustion products from the combustion chamber. The outlets and inlets are surrounded by annular sealing lips provided on one end face of the holder and arranged to abut against the other end face of an adjoining holder so that the inlets and outlets of one holder communicate with the corresponding inlets and outlets of the adjoining holder but are sealed from the atmosphere.
A combination as defined in claim 1, wherein said holder consists of elastomeric material.
Claim 2
Dependent Claim
14 words
A combination as definEd in claim 2, wherein said elastomeric material is natural rubber.
Claim 3
Dependent Claim
15 words
A combination as defined in claim 2, wherein said elastomeric material is a synthetic rubber.
Claim 4
Dependent Claim
20 words
A combination as defined in claim 2, wherein said elastomeric material has a Shore-A hardness of between 50 and 95.
Claim 5
Dependent Claim
18 words
A combination as defined in claim 1 wherein said members include a partition and at least one electrode.
Claim 6
Dependent Claim
39 words
A combination as defined in claim 6, wherein said members define with said holder a plurality of chambers extending between said members and wherein said holder is provided with an inlet and an outlet for each of said chambers.
Claim 7
Dependent Claim
57 words
A combination as defined in claim 7, wherein said holder has two end faces at least one of which is substantially parallel with the planes of said members and wherein said inlets and outlets have portions extending between said end faces, said one end face being provided with annular sealing lips each surrounding one of said portions.
Claim 8
Dependent Claim
111 words
In a fuel cell, a combination comprising a plurality of substantially platelike members; an annular holder surrounding said members and having a substantially ring-shaped internal spacer collars adjacent to marginal portions of said members so as to maintain said members in predetermined positions with reference to each other, said holder consisting of electrically insulating material and being provided with at least one channel; electrical conductor means extending through said channel and connected to one of said members; and at least one annular lip in said channel integral with said holder and sealingly engaging said conductor means the spacer collars being so constructed to permit insertion of said members into said holder.
