Abstract

An electrochemical cell includes a fuel electrode configured to operate as an anode to oxidize a fuel when connected to a load, and configured to operate as a cathode when connected to a power supply. The fuel electrode comprises a plurality of scaffolded electrode bodies, wherein the scaffolded electrode bodies are of varying size. The electrode bodies are of a larger size at positions distal from a charging electrode configured to act as an anode when connected to the power supply, and of a smaller size at positions proximal to the charging electrode. When connected to a load, the scaffolded electrode bodies-containing fuel electrode acts as the electrochemical cell anode and electrodeposited fuel is oxidized.

Description

[0001] This application claims priority to US Provisional Application Serial No. 61 / 358,339, the entire contents of which are incorporated herein by reference. technical field [0002] The present application relates to electrochemical cells for generating electrical power, and more particularly to a cell using electrodeposited fuel. Background technique [0003] US Patent Application Publication Nos. 2009 / 0284229A1 and 2011 / 0086278A1 each disclose a metal-air battery having an anode formed from a series of spaced apart permeable electrode bodies. The metal fuel is reduced and electrodeposited on the electrode body. One challenge with this type of design is ensuring that growth does not prematurely short adjacent electrode bodies together, thus reducing the likelihood of dense growth between electrode bodies. [0004] The present application seeks to provide an improved cell structure for use in cells such as those in the above-referenced applications, in which the fuel is ...
