摘要:
The invention relates to a porous body with a density of 40 to 70%, made from an iron alloy, with 0.01 to 2 wt. % of mixed oxide made up of at least one oxide compound of one or metals from the group Y, Sc, or rare earth metals and at least one further oxide compound of one or more metals of the group Ti, Al, or Cr. The porous body shows no degradation at application temperatures of 900°C, is further characterised by an exceedingly high resistance to corrosion and is particularly suitable as support substance for application in high temperature fuel cells.
摘要:
The invention relates to a method for producing a molding by means of the following steps: producing a molding compound, plasticizing the molding compound in an extruder and removing it via a slotted nozzle, feeding the green product into a planishing mill, smoothing the green product by at least one planishing process, chemical and/or thermal debindering and sintering. The continuously operating method enables a cost-efficient production of preferably flat products having a high surface quality.

The invention relates to a method for depositing an electrically conducting, preferably perowskitic, layer, by means of a pulsed sputter process. The layer has low diffusivity for elements of the ferrous group and is particularly suitable for application in SOFC fuel cells.

A fuel cell (1) has a plate (2) manufactured by powder metallurgy. The plate is manufactured in one piece and comprises a porous substrate area (4), onto which the electrochemically active cell layers (6) are applied, and a gas impermeable edge area (5) which is provided with perforations through which gas can pass (17, 18).
