Claim 0:
1. A rechargeable electrochemical cell comprising:
a fuel electrode comprising
a) a first corrugated portion formed of electrically conductive material, the first corrugated portion defining a first corrugation axis and defining a plurality of first apertures therethrough,
b) a second corrugated portion formed of electrically conductive material, the second corrugated portion defining a second corrugation axis offset from the first corrugation axis and defining a plurality of second apertures therethrough,
c) a third corrugated portion formed of electrically conductive material, the third corrugated portion defining a third corrugation axis aligned with the first corrugation axis and defining a plurality of third apertures therethrough, and
d) electrode attachments attaching the first corrugated portion and the third corrugated portion to opposite sides of the second corrugated portion;

a cathode;
an ionically conductive medium communicating the fuel electrode and the cathode; and
a metal fuel exposed to the ionically conductive medium, the metal fuel electrochemically despositable on the first corrugated portion, the second corrugated portion, and the third corrugated portion of the fuel electrode.
