POWDER CONTAINING ELONGATED GRAINS AND THE USE THEREOF FOR PRODUCING AN ELECTRODE FOR A SOLID OXIDE FUEL CELL

摘要

The invention relates to a powder made of a set of grains, characterised in that the percentile 10 of the cumulated granulometric distribution of the grain sizes, expressed from fines, D10, is higher than or equal to 4 µm, at least 40 number % of the grains having a shape factor R between the length and the width higher than 1.5. preferably, the grains consist of a material selected from ceramics, cermets and mixtures of same. The powder according to the invention is used to produce a porous material, especially for producing solid oxide fuel cell elements (SOFC)1, especially an electrode of such a cell.
