Abstract:
1. A fuel supply system for at least one fuel cell battery, comprising: a reservoir container for storing a quantity of electrochemical anode material and a quantity of reaction products, said reservoir container including at least two isolated chambers of inversely variable volume; first means for communicating anode material between at least one cell connected to said reservoir container and a first of said chambers in said reservoir container; second means for communicating reaction products between the cell and a second of said chambers in said reservoir container; and means for varying the respective volumes of said first and second chambers as fresh anode material is delivered to said cell and reaction products are delivered to said reservoir; wherein said reservoir container has at least one flexible wall and the system includes means for compressing the flexible wall to force anode material out of said reservoir and into the at least one fuel cell element.
