US Classification:

429512

Abstract:

An electrochemical cell system for generating electrical power is disclosed. The electrochemical cell system comprises a plurality of fluidly connected electrochemical cells. Each electrochemical cell comprises an anode and a cathode. The anode is configured to permit a fluid comprising at least an electrolyte to flow in contact therewith to oxidize a fuel. The cathode is permeable to an oxidizer and is configured to receive electrons to reduce the oxidizer. The cathode and the anode are spaced apart to define a gap therebetween for receiving the fluid flow. The plurality of electrochemical cells are connected in fluid flow series such that, for each pair of fluidly connected electrochemical cells, the fluid flows from a first cell of the pair of cells to a second cell of the pair of cells. The plurality of electrochemical cells are connected electrically in series such that, for each pair of fluidly connected electrochemical cells, the cathode of the first cell of the pair is electrically connected to the anode of the second cell of the pair.

International Classification:

H02J 7/00

US Classification:

320137

Abstract:

An electrochemical cell includes a fuel electrode configured to operate as an anode to oxidize a fuel when connected to a load. The cell also includes an oxidant electrode configured to operate as a cathode to reduce oxygen when connected to the load. The fuel electrode comprises a plurality of scaffolded electrode bodies. The present invention relates to an electrochemical cell system and method of resetting the electrochemical cell by applying a charge (i.e. voltage or current) to the cell to drive oxidation of the fuel, wherein the fuel electrode operates as an anode, and the second cell operates as a cathode, removing uneven distributions of fuel that may cause premature shorting of the electrode bodies to improve capacity, energy stored, and cell efficiency.
