摘要： During the humidification of operating gases for a fuel cell (101), the operating gases cool to such an extent as a result of the loss of evaporation heat that they cannot absorb enough humidity to prevent damage to the membrane of the fuel cell (101). To solve this problem, a fuel cell assembly (50) comprising a humidification cell (1), which contains a planar heating element (7), is provided. The humidification cell (1) is configured in terms of shape, location and materials in the same way as a fuel cell (101) of the fuel-cell stack (50).

摘要： When an insulator (1) is used in a humid atmosphere, the cooling thereof causes a humidity condensation, which is deposited on the insulator (1) surface. Drops of water formed by the humidity condensation are connected to each other that a water film substantially reducing the insulation resistance of the insulator (1) is formed. In order to solve said problem, the inventive insulator (1) is provided, at least partially, with a hydrophobe surface (6). In such a way, the water layers formed by condensation are drained off the surface or detached therefrom without connection and the drops of water produced by condensation are unable to be bound to each other, thereby making it possible to maintain a desired high insulation resistance.

摘要： The invention relates to a humidification cell (1) of a fuel cell assembly (41), comprising a water-permeable membrane (5) located between two external plates (9) of said humidification cell (1). One section of the surface of the membrane (5) is fitted to at least one of the external plates (9) and is thus partially covered by the external plate (9). This reduces the humidification capability of the membrane (5). To solve this problem, the inventive humidification cell (1) has a water-permeable supporting element (7a, 7b), which is located between the membrane (5) and one of the external plates (9).

摘要： The composite conductor plate (5) of a low-temperature fuel cell (1) poses the following problem: it must be extremely corrosion-resistant to pure oxygen that is humidified by water and to pure hydrogen and must at the same time be able to be processed mechanically. To solve said problem, the invention provides a composite conductor plate (5) consisting of 50 to 65 wt. % Ni, 12 to 22 wt. % Cr, 10 to 18 wt. % Mo, 4 to 10 wt. % Fe and 0.5 to 5 wt. % W.

摘要： The invention relates to a fuel cell block (40) that comprises elements (1, 25a-b, 42a-e, 51, 52) that are stacked. At least two adjacent elements (1, 25a-b, 42a-e, 51, 52) define an intermediate space (7, 27, 71) between them. Radial channels (8a, 8b, 8c, 35, 72, 76) are configured between the two elements (1, 25a-b, 42a-e, 51, 52) or in one of the two elements (51, 52), said channels communicating with the intermediate space (7, 27, 71). At least one of the radial channels is configured as a blind channel (9a, 9b, 74, 77) and, unlike the radial channels (8a, 8b, 8c, 35, 72, 76), is not used for a medium flowing into or out of the intermediate space (7, 27, 71). The number of radial channels that are configured as blind channels (9a, 9b, 74, 77) influences the quantity of operating medium flowing through the intermediate space (7, 27, 71).
