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.
