Abstract: A fuel electrode incorporates a first and second corrugated portion that are attached to each other at offset angles respect to their corrugation axis and therefore reinforce each other. A first corrugated portion may extend orthogonally with respect to a second corrugated portion. The first and second corrugated portions may be formed from metal wire and may therefore have a very high volumetric void fraction and a high surface area to volume ratio (sa/vol). In addition, the strands of the wire may be selected to enable high conductivity to the current collectors while maximizing the sa/vol. In addition, the shape of the corrugation, including the period distance, amplitude and geometry may be selected with respect to the stiffness requirements and electrochemical cell application factors. The first and second corrugated portions may be calendared or crushed to reduce thickness of the fuel electrode.

Abstract: An exemplary electrochemical cell incorporates at least a first battery electrode, such as a zinc electrode, at least a second battery electrode, such as a reversible metal electrode such as nickel, and at least an oxidant reduction electrode, such as an air cathode. The oxidant reduction electrode(s) is configured in a cell housing such that it is essentially orthogonal to the first and second electrodes. The cell housing contains electrolyte therein and the electrodes are immersed, at least partially, in the electrolyte. The positioning of the oxidant reduction electrode(s) on the side of the cell and relatively perpendicular to the first and second (metal) electrodes, allows for more consistent ionic resistance across all the metal electrodes. Optionally, a fourth or oxygen evolving electrode may be provided in the cell housing, horizontal, orthogonal, and below the first and second electrodes to provide oxygen bubbles for mixing the electrolyte.
