1. An electrochemical zinc-oxygen cell comprising:

  • a tubular catalyst containing oxygen diffusion cathode which is electrically conducting and oxygen porous, said tubular cathode providing a tubular through passage open at each end;

    a concentric tubular ion conducting separator surrounding and in ionic contact with said oxygen cathode;

    a concentric tubular electrically conducting anode spaced radially from and surrounding said separator forming an annular electrolyte space between said separator and said anode, said annular electrolyte space providing an annular through passage open at each end;

    means for pressurizing and passing oxygen containing gas through and in contact with the central portion of said tubular oxygen diffusion cathode, said oxygen containing gas entering at one end and exiting at the other end of said tubular through passage;

    means for passing liquid electrolyte through said annular electrolyte space in ionic contact with said ion conducting separator and said anode, said electrolyte entering at one end and exiting at the other end of said annular through passage and;

    an anode active zinc material in contact with said electrolyte.
