摘要： The aim of the invention is to produce complete high temperature fuel cells by means of thermal injection processes (e.g. atmospheric plasma injection, vacuum plasma injection, high speed flame injection). The production method is especially simplified and is economical by virtue of the fact that the carrier substrate is also produced on a base with the aid of a thermal injection method. The base or an intermediate layer placed thereon can be advantageously dissolved or decomposed such that the carrier substrate provided with layers arranged thereon can be separated in a very simple manner from the base which becomes unnecessary. Said method advantageously enables the production of all layers of a high temperature fuel cell, exclusively with the aid of a thermal injection method.

摘要： Disclosed is a modified powder injection molding method which is advantageously used for producing highly porous, near net-shaped parts having complex geometries from initial metallic and/or ceramic powders. The placeholders that are used are non-toxic and can be quickly and almost entirely removed from the parts. Said placeholders make it possible to specifically adjust the pore sizes of the parts within a range of 20 ?m to 2 mm and the porosities thereof within a range of 10 to 85 percent by volume, the distribution of pores being very homogeneous. The duration of the entire process is determined to a considerable degree by the removal of the binder and the placeholders. The total time required from the step of preliminary surface-active binder removal is no more than 14 to 20 hours, even if preliminary thermal binder removal is added (for metal powders and ceramic powders

摘要： The invention relates to a method for producing highly porous, metallic moulded bodies. The inventive method consists of the following steps: a metallic powder used as a starting material is mixed with a dummy; a green body is pressed out of the mixture; the green body is subjected to conventional mechanical machining, the dummy advantageously increasing the stability of the green body; the dummy material is thermally separated from the green body by means of air, a vacuum or an inert gas; and the green body is sintered to form the moulded body and is then advantageously finished. Suitable materials for the dummy are, for example, ammonium bicarbonate or carbamide. The mechanical machining carried out before the sintering advantageously enables a simple production close to the desired final contours, even for complicated geometries of the moulded body to be produced, without impairing the porosity, and without high wear of the tools. The workpiece is advantageously sufficiently stable in terms of pressure for the green machining as the dummy material is still present in the pores of the green body during the machining.
