Control of edge effects of oxidant electrode
First Claim
1. An electrode assembly comprising:
- a. a porous electrode (40) having a first (122a) and second (122b) exterior face with a cavity (114) formed in the interior between said exterior faces thereby having first (120a) and second (120b) interior faces positioned opposite the first and second exterior faces;
b. a counter electrode (68) positioned facing each of the first and second exterior faces of the porous electrode;
c. means (83) for passing an oxidant through said porous electrode; and
d. screening means (126) for blocking the interior face of the porous electrode a greater amount than the blocking (124a and 124b) of the respective exterior face of the porous electrode, thereby maintaining a differential of oxidant electrode surface between the interior face and the exterior face.

Abstract
Described is an electrode assembly comprising;
a. a porous electrode having a first and second exterior face with a cavity formed in the interior between said exterior faces thereby having first and second interior faces positioned opposite the first and second exterior faces;
b. a counter electrode positioned facing each of the first and second exterior faces of the porous electrode;
c. means for passing an oxidant through said porous electrode; and
d. screening means for blocking the interior face of the porous electrode a greater amount than the blocking of the respective exterior face of the porous electrode, thereby maintaining a differential of oxidant electrode surface between the interior face and the exterior face.
The electrode assembly is useful in a metal, halogen, halogen hydrate electrical energy storage device.
