    摘要： An electrode for a fuel cell of the invention comprises a cation-exchange resin, carbon particles and a catalyst metal which is amorphous. The electrode has high activity, a high catalyst utilization and high CO tolerance and is highly active in the electrochemical oxidation reaction of methanol. Furthermore these qualities of the electrode were extremely improved when the catalyst metal was loaded mainly on sites where the surface of the carbon particles contacts proton-conductive passages in the cation-exchange resin. Consequently, a fuel cell with the electrode of the invention has a high output current and a long life, and can be produced at low cost.

    摘要： The non-aqueous electrolyte secondary battery of the present invention comprises, e.g., a positive electrode 6, a negative electrode 5, a polymer membrane 1 containing carbon powder or the like, and a separating membrane layer 7 for preventing shortcircuiting. A carbon powder, silicon powder, tin powder or aluminum powder 2 contained in the polymer membrane 1 containing carbon powder or the like absorbs as a lithium-absorbing material metallic lithium powders 3 or metallic lithium dendrite 4 which has been produced from the negative electrode 5 due to charge or discharge and takes no part in charge or discharge. This lithium-absorbing material is less reactive than the metallic lithium powders 3 or metallic lithium dendrite 4 and thus enhances the safety of the battery and controls shortcircuiting between the positive electrode and the negative electrode due to metallic lithium dendrite, making it possible to drastically improve charge and discharge cycle life performance.
