Abstract
Abstract An electrolyte control system for a fuel cell which has an anode and a cathode spaced by an electrolyte carrying matrix wherein porous capillary conduits communicate from an electrolyte reservoir to points uniformly along the matrix. For example, the porous capillary conduits can be positioned uniformly along the matrix adjacent the cathode and thereby supply electrolyte directly to the cathode, and to the anode and matrix at whatever rate the matrix will absorb the electrolyte.
