Abstract: A method for the combined production of electricity and nitric oxide,: comprising the steps of: providing an SOFC comprising an anodic side comprising a solid gas-permeable anode, a gas inlet and a gas outlet, a cathodic side comprising a solid gas-permeable cathode and a gas inlet and a gas outlet, and a fully dense solid electrolyte, separating the cathodic side from the anodic side; introducing an oxygen-containing gas in the inlet of the cathodic side of the SOFC; introducing an ammonia-containing gas stream in the inlet of the anodic side of the SOFC; collecting nitric oxide at the outlet of the anodic side and collecting a current flowing between the anodic side and the cathodic side.

Abstract: Use of an austenitic stainless steel wherein the chemical composition comprises 10-20 weight % nickel, 10-20 weight % chromium, 30-50 weight % iron, maximum 17 weight % of another element or elements and the balance iron and/or chromium and/or nickel as construction material in a device or structural components that are exposed to an oxygen and/or a hydrogen and/or a hydrofluoric acid environment.

Abstract: The present invention relates to a cell stack having at least one electrochemical cell arranged between a first end plate connected to an electrical bolt and a second end plate connected to another electrical bolt, said stack having a housing, means for providing fixed support of said stack to said housing and means for maintaining a constant load over said cell stack. Said means for maintaining a constant load comprise an elastic pad inserted into the space between said cell stack and said housing wall. The cell stack is applicable in the area of PEM fuel cells and PEM water electrolyser cells.
