|Title:||Preparation and characterisation of porous electrodes from nickel powder for fuel cells|
Raj, I Arul
|Abstract:||Porous gas diffusion electrodes are used in fuel cells. The essential requirement of the porous electrodes is to establish an internal gas/liquid interface as long as the current is drawn from the cells. INCO nickel-255 powder is used for making porous electrodes by powder compaction and sintering techniques. The porosity and pore-size distribution in the electrodes are correlated with the compaction pressure, sintering temperature, amount of pore formers and particle sizes of catalysts. A method for the fabrication of two layer and three layer electrodes with graded porosity is outlined.|
