A fuel cell or an electrolyser includes at least one electrode and at least one polymer electrolyte membrane. The electrode includes a catalyst system comprising a carrier metal oxide and a catalyst material. The catalyst material is formed by an electrically conductive metal phosphate in the form of a metaphosphate of the general chemical formula Me(PO), where Me=metal, z=valency of the metal Me, and n is within the range of 1 to 10.

Fuel cell or electrolyser

An electrode unit (), in particular for a redox flow cell (), including at least one metallic substrate () and a coating () which is applied to the substrate (), wherein the coating () includes at least one protective layer () which is formed from titanium-niobium nitride (TiNbN) and/or titanium-niobium carbide (TiNbC). A redox flow cell (), in particular a redox flow battery, having at least one such electrode unit () is also provided.

Electrode unit and redox flow cell

A catalytic arrangement for an electrolyzer system or a fuel cell system includes a catalyst support unit and a catalyst layer, wherein the catalyst layer has a carbon matrix with a metal, non-metal and/or metalloid doping.

Energy storage is accomplished by producing hydrazine carbonate and later reconverting the hydrazine carbonate to release the energy. Sea water is firstly used in an electrolysis process to prepare hypochlorite. The hypochlorite reacts as a result of introduction of ammonia to produce monochloramine and then hydrazine. The hydrazine reacts as a result of introduction of carbon dioxide to give hydrazine carbonate. To release the energy, the hydrazine carbonate liberates hydrogen or at least a hydrogen-containing gas by reaction over a noble metal-free catalyst. The hydrogen may then be enriched before being fed to a fuel cell.
