Use of aluminium-aluminium oxide composite material

摘要

Electrically conductive components for high temperature fuel cells, especially electrodes and bipolar plates for molten carbonate fuel cells, consist of a mixture of (preferably 40-70%) aluminium oxide and (preferably 30-60%) aluminium. Also claimed is production of the above components by (i) dry pressing fine Al2O3 powder in a mould and then saturating with aluminium in an aluminium melt; or (ii) mixing fine Al2O3 powder with fine Al powder, dry pressing the mixture in a mould and then sintering at high temperature. Further claimed is the use of a mixture of Al2O3 and Al for producing current conducting components for high temperature fuel cells.
