Title:
METAL FUEL CELL WITH MOVABLE CATHODE
Document Type and Number:
WIPO Patent Application WO2001097313
Kind Code:
A3
Abstract:
An air depolarized cell with at least one movable cathode element (3) disposed in an active anode metal material which is in a fluid or paste state. The cathode element(s) continuously moves to maintain electrochemical proximity with active anode material as the active anode material is converted into electrochemical cell reaction product. In one embodiment, formation of cell reaction products of increased volume relative to initial anode volume serves to propel the movable cathode through the anode material. Viscosity of the fluid or anode paste is adjusted to ensure cathode movement relative to active anode for maximized utilization.
