Abstract
Abstract A power module of the electrochemical battery type wherein shunt losses along the side edges of the anodes disposed generally parallel to the electrolyte path are prevented by the anode side edges being sealed relative to the casing by the casing being constructed with internal side walls which are deformable under gaseous pressure to maintain sealing contact with the cell units.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
145 words
A power module casing for receiving plural cell units in adjacent relation and wherein each cell unit includes at least a consumable element with the cell units being progressively moved towards one end of said casing as the consumable elements are consumed, said casing being elongated and of a generally rectangular cross section and including ends and first and second opposing sides, manifold plates within said casing in spaced adjacent relation to said first sides and defining in combination therewith electrolyte supply and return manifolds, and sealing plates within said casing adjacent said second sides, said sealing plates extending at least between said manifolds, and means for introducing a fluid under pressure between each sealing plate and its respective second side for urging each sealing plate inwardly of said casing for sealing engagement with edges of cell units when such cell units are disposed therebetween.
Claim 2
Dependent Claim
145 words
A power module casing for receiving plural cell units in adjacent relation and wherein each cell unit includes at least a consumable element with the cell units being progressively moved towards one end of said casing as the consumable elements are consumed, said casing being elongated and of a generally rectangular cross section and including ends and first and second opposing sides, manifold plates within said casing in spaced adjacent relation to said first sides and defining in combination therewith electrolyte supply and return manifolds, and sealing plates within said casing adjacent said second sides, said sealing plates extending at least between said manifolds, and means for introducing a fluid under pressure between each sealing plate and its respective second side for urging each sealing plate inwardly of said casing for sealing engagement with edges of cell units when such cell units are disposed therebetween.
Claim 3
Dependent Claim
15 words
The power module casing of claim 1 wherein said sealing plates are thin flexible sheets.
Claim 4
Dependent Claim
19 words
The power module casing of claim 1 wherein said sealing plates are thin flexible sheets of a plastics material.
Claim 5
Dependent Claim
25 words
The power module casing of claim 1 wherein said manifold plates extend between said sealing plates and are in edge to face sealing engagement therewith.
Claim 6
Dependent Claim
16 words
The power module casing of claim 1 wherein said fluid under pressure is an inert gas.
Claim 7
Dependent Claim
72 words
The power module casing of claim 1 together with a series of cell units within said casing, each said cell unit including a cathode and a consumable anode, means associated with said cathode for directing electrolyte from said supply manifold across the face of said anode and into said return manifold, and said sealing plates engaging sides of said cell units between said electrolyte manifolds and preventing electrolyte flow around said anodes.
Claim 8
Dependent Claim
26 words
The power module casing of claim 1 wherein side edges of said anodes have an electrolyte resistant covering in sealed sliding contact with said pressure plates.
Claim 9
Dependent Claim
17 words
The power module casing of claim 7 wherein said covering is formed of a plastics material film.
