Abstract: The invention concerns a half-cell (H1) of an electrolytic cell (EZ) for an electrolyzer (EY). The half-cell (H1) has an anode part-plate (AP) with perpendicular elevations (NP). Arranged on an upper side of the perpendicular elevations (NP) of the anode part-plate (AP) is an anode-transporting layer (AT). The half-cell (H1) has a membrane (MB), which is arranged on a side of the anode-transporting layer (AT) that is facing away from the elevations (NP) and which is permeable to specified charge carriers. In this case, the anode-transporting layer (AT) has a graduated pore structure, in which a respective diameter of the pores in the anode-transporting layer (AT) decreases in a direction perpendicularly towards the membrane (MB).

Abstract: A combustion section of a gas turbine includes an annular combustion chamber, a burner arrangement upstream of the combustion chamber, an annular compressor diffusor, and an annular combustion casing. The combustion casing has an outer section wall, an upstream section wall, and an inner section wall. The inner section wall extends along the rotor axis and is arranged between the burner arrangement and the compressor diffusor. A shielding is attached to the inner section wall at the side facing the rotor axis with a free space in-between at least. An outer diffusor wall of the compressor diffusor extends in axial direction up to the upstream half of the shielding.

Abstract: A method of applying a plurality of energy beams in the additive manufacture of a component includes a) providing a first and a second energy beam, each set up for the irradiation of a layer of a powder bed, wherein the first beam scans over a first irradiation area and the second beam scans over a second irradiation area, wherein the first and second irradiation areas are substantially arranged adjacent to each other and form part of a manufacturing plane, and b) assigning a scan vector to be scanned in the first irradiation area by the second energy beam, when a melt pool generated by the second energy beam during the scan of the vector is expected to cause less overlap with a powder bed outside of the component's geometry than a melt pool generated by the first energy beam would cause during the scan of the vector.

Abstract: A gas turbine engine having a pre-swirler adjustability is presented. The pre-swirler includes a pre-swirler insert installed in a component enclosed by a cover. The component includes an inner compressor exit diffusor enclosed by an outer casing or a shaft cover enclosed by the inner compressor exit diffusor. The pre-swirler is adjustable by replacing the pre-swirler insert. An access port including an access window is arranged on the cover. The access port gives access to the pre-swirler insert for replacement through the access window. The access window includes a manhole or combustor assembly installation hole on the outer casing, or a cutout on the inner compressor exit diffusor. The access port allows adjusting the pre-swirler by replacing the pre-swirler insert installed in the component without lifting the cover enclosing the component.

Abstract: The invention relates to a method for operating an electrolysis plant having an electrolyser for generating hydrogen and oxygen as product gases, and a control unit. At least the hydrogen product gas, which also contains oxygen as an external gas, is compressed. According to the invention, the energy required in the purification of the foreign gas in the product gas of the electrolysis plant can be reduced by making optimum use of the heating of the product gas by the compression process, whereby the hydrogen product gas is subsequently fed to a recombiner which contains a catalyst in which the oxygen recombines with the hydrogen to form water. The invention also relates to an electrolysis plant designed for efficient product gas purification, by means of which hydrogen purified from oxygen as an impurity gas can be produced as a product gas.
