Abstract: An electrolyzer (100) comprising a first (110) and a second (120) electrode and an ion exchange membrane (130) arranged in-between the first and the second electrode. Each electrode comprises an electrically conductive element (111, 121). At least one of the electrodes also comprises a catalyst structure (140) comprising an electrically conductive material. The electrolyzer also comprises at least one feeding means (160, 320, 330, 410), wherein the feeding means (160, 320, 330, 410) is arranged to introduce a variable electromagnetic field into the electrolyzer (100). The variable electromagnetic field is arranged to create a temperature gradient in the electrolyzer (100) by increasing a temperature of the catalyst structure (140).
