(JP7240204-A)      A gas-liq. permeable porous electrode comprises a non-uniform electrode layer supported on at least one side of a substrate and comprising a region near a bulk gas inlet having a different amt. of a component per unit area than a region remote from this area. When the component is an electrocatalyst the amt. of component is not increased between a gas inlet and outlet.    Also claimed is a membrane electrode assembly where at least one of the electrodes is as above.    Further claimed is a fuel cell comprising the electrode above.    Also claimed is a process for the prodn. of an electrode as above comprising prepn. of components and solvent into paste which is transferred on to the substrate to form the non-uniform electrode above.    USE -   For solid polymer fuel cells, metal-air batteries, ozone-generating cathodes, and gas sensors.    ADVANTAGE -   Electrochemical performance is improved (Fig.) using the same total electrocatalyst loading.
