Abstract

A power-to-X system having an electrolyzer and an energy converter which are connected together via a hydrogen line. The system additionally has a chemical reactor for catalytically removing oxygen, a first heat exchanger, a water separator, a store, and a humidifier which are connected into the hydrogen line in the stated order one behind the other between the electrolyzer and the energy converter. A second heat exchanger is arranged in the hydrogen line such that a first side of the second heat exchanger is arranged in front of the first heat exchanger and a second side of the second heat exchanger is arranged downstream of the water separator in the hydrogen line.
