Abstract

PURPOSE: To reduce the hydrogen overvoltage and then increase the life time of use for the negative electrode for hydrogen generation, by providing the coated layer composed of the Ni metal and the platinum group metal on the surface of a substrat composed mainly of Ni and furthermore forming coated layer of the platinum group metal onto the first coated layer.
CONSTITUTION: The first layer is formed by applying once or several times and alternately the thin layers of the Ni metal and the platinum group metal each onto the coarsened surface of the substrate composed mainly of Ni or onto the porous plate, for example, by the plating, coating of solution or electrodeposition method. And the content ratio between the Ni metal and the platinum-group metal in the first layer can be varied over a wide range. Then the second layer of the platinum group metal is formed on the first layer via the electroplating or the chemical plating. After this, the burning is carried out in the air or the inactive gas to increase the resistance to corrosion and then the life time of the electrode for hydrogen generation.
