Abstract
An alkaline cell having an anode with a solid particle gelling agent centrally disposed therein for increasing concentration of zinc powder closer to the separator and cathode. The anode initially contains zinc powder, gelling agent and electrolyte solution. A dry solid gelling agent, preferably configured as a cylindrical rod, is disposed into a gel anode and allowed to absorb electrolyte solution, the rod thereby swelling in size to consume greater volume while concentrating the zinc powder toward the separator.
