Abstract: Die Erfindung betrifft ein Verfahren zur Herstellung von kohlenstoffhaltigen Produkten unter Verwendung einer elektrochemischen Zelle (0) von besonderer Bauweise. Ihr lag die Aufgabe zu Grunde, eine elektrochemische Zelle (0) für die Reduktion von Kohlenstoffdioxid anzugeben, die sich aus preisgünstigeren Materialien realisieren lässt. Gelöst wird diese Aufgabe dadurch, dass als elektrokatalytisch aktive Anode (1) ein textiles Flächengebilde verwendet wird, welches nickelhaltige Liniengebilde enthält.

Abstract: A method for operating a water electrolyzer includes applying a voltage to a water electrolysis cell such that a current having a target current value flows through the water electrolysis cell and stopping the current that flows through the water electrolysis cell upon a voltage applied to the water electrolysis cell being increased to a predetermined threshold value or more when a water electrolysis reaction is performed.

Abstract: Systems and methods are provided for water electrolysis. The system includes an ion exchange membrane, a first electrode catalyst layer on a first side of the ion exchange membrane, wherein the first electrode catalyst layer includes a transition metal-phosphorus-based compound on the first side of the ion exchange membrane, and a second electrode catalyst layer on a second side of the ion exchange membrane opposite the first side. In some embodiments, the first electrode catalyst layer is electroplated to the first side of the ion exchange membrane. In some embodiments, the second electrode catalyst layer includes a compound comprising the same transition metal as the first electrode catalyst layer.

Abstract: A membrane electrode assembly includes a first electrode, a second electrode, and an anion exchange membrane disposed between the first electrode and the second electrode. The first electrode includes a first metal mesh, a first catalyst layer wrapping the first metal mesh, a second metal mesh, and a second catalyst layer wrapping the second metal mesh. The first metal mesh is disposed between the anion exchange membrane and the second metal mesh. The second metal mesh is thicker than the first metal mesh, and the first catalyst layer is thicker than the second catalyst layer. The second catalyst layer is iron, cobalt, manganese, zinc, niobium, molybdenum, ruthenium, platinum, gold, or aluminum. The second catalyst layer is crystalline.
