  • Aluminum anode alloy for primary high power density alkaline fuel cells and batteries
    Patent number: 4150204
    Abstract: A tin and mercury free aluminum alloy of specific composition for use as an node in fuel cells and electrochemical couples and particularly in a silver oxide-aluminum battery comprising high purity aluminum alloyed with gallium and magnesium in specified quantities. The aluminum in combination with the gallium provide desired unique electrochemical properties. The magnesium, when the anode material is suitably heat treated, increases the tensile modulus of the alloy.
    Type: Grant
    Filed: June 15, 1978
    Date of Patent: April 17, 1979
    Assignee: The United States of America as represented by the Secretary of the Navy
