Abstract (en)
[origin: CA3225319A1] The invention relates to a method for operating an electrolysis plant having an electrolyser for generating hydrogen and oxygen as product gases, and a control unit. At least the hydrogen product gas, which also contains oxygen as an external gas, is compressed. According to the invention, the energy required in the purification of the foreign gas in the product gas of the electrolysis plant can be reduced by making optimum use of the heating of the product gas by the compression process, whereby the hydrogen product gas is subsequently fed to a recombiner which contains a catalyst in which the oxygen recombines with the hydrogen to form water. The invention also relates to an electrolysis plant designed for efficient product gas purification, by means of which hydrogen purified from oxygen as an impurity gas can be produced as a product gas.
