Title: Improvements in the manufacture of gas-diffusion electrodes
IPC: B22F3/11
Filed: 1966-04-25
Abstract: A process of making sintered gas diffusion electrodes comprises preparing a suspension in mercury, preferably by electrolysis, of at least one of the metals Fe, Co or Ni, removing some of the mercury to form a granular residue which is then hot pressed in vacuo or an inert or protective atmosphere to form a sintered porous body.  The suspension is formed by electrolyzing an aqueous solution of the metal salt e.g. the sulphate using mercury electrodes, a current intensity of 500-2000 A/sq.m. and a temperature of 20 DEG -80 DEG C., the metal of the suspension having a grain size of 2-10 microns and being present in a concentration of 0.4%-0.5% by weight.  Mercury is removed by centrifuging or filtering to form a residue containing 3%-10% of the metal.  The residue is hot pressed in a foraminous or perforated metal mould at 200 DEG -370 DEG C.  Hydrogen is the preferred atmosphere and the sintered compact is quenched in methyl alcohol before removing the hydrogen atmosphere.  The residual mercury forms no more than 0.15% weight of the electrode.
