MICROBIAL FUEL CELL CATHODE ASSEMBLY
First Claim
1. A microbial fuel cell cathode assembly comprising a catalyst and an electrically conductive catholyte wicking member having a catalyst contacting surface in contact with the catalyst, an electrical contact region for contacting an electrical connector, and a catholyte supply region for receiving catholyte from a catholyte supply, wherein the electrically conductive catholyte wicking member is operable to wick received catholyte from the catholyte supply region to form a film of catholyte on a part of the surface of the catalyst such that a part of the surface of the catalyst is in contact with the film of catholyte and a part of the surface of the catalyst is in contact with a gas pathway arranged to supply oxygen to the catalyst.

Abstract
Disclosed is a microbial fuel cell cathode assembly comprising a catalyst (6) and an electrically conductive catholyte wicking member (5) having a catalyst contacting surface (5a) in contact with the catalyst, an electrical contact region (5c) for contacting an electrical connector, and a catholyte supply region (5b) for receiving catholyte from a catholyte supply (9), wherein the electrically conductive catholyte wicking member is operable to wick received catholyte from the catholyte supply region to form a film of catholyte on a part of the surface of the catalyst such that a part of the surface of the catalyst is in contact with both the film of catholyte and a part of the surface of the catalyst is in contact with a gas pathway arranged to supply oxygen to the catalyst.
