A cathode for an electrolyser. It comprises porous conductive material which includes sintered nickel impregnated with a catalyst, characterized in that said catalyst is a molybdate of nickel or iron or mixtures thereof. The invention is used for manufacturing hydrogen by electrolysing an aqueous alkaline solution.

Cathode for an electrolyser

A bipolar electrode for an electrolyzer. It is characterized in that the anode surface and the cathode surface of said electrode both comprise a porous conductive material which includes sintered nickel previously impregnated with nickel molybdate. The invention is used for manufacturing hydrogen by electrolyzing an aqueous alkaline solution.

Bipolar electrode for an electrolyzer

A bipolar electrode for an electolyser. It is characterized in that the anode surface and the cathode surface of said electrode both comprise a porous conductive material which includes sintered nickel previously impregnated with nickel molybdate. The invention is used for manufacturing hydrogen by electrolysing an aqueous alkaline solution.

Bipolar electrode for an electrolyser

The invention relates to a rechargeable electrochemical system suitable for use in an electric vehicle. It comprises a battery comprising at least one positive electrode depolarized by air, at least one negative collector, a tank, an electrolyzer comprising at least one positive electrode and one negative electrode, an electrolyte bearing in suspension the negative active material. The electrolyte is caused to flow either between the tank and the battery or between the electrolyzer and the tank, wherein the total volume of the alkaline electrolyte, bearing in suspension a negative active material containing 250 g to 350 g per liter of equivalent zinc, lies between one and a half and three times the internal volume of the electrolyzer.
