This patent describes a zinc-bromide electrochemical cell. It comprises: a cathode element comprising a pressure-molded porous composite comprising electrically conductive particulate carbon selected from the group consisting of carbon black, graphite and mixtures thereof having a particle size distribution of 0 to 45 {mu}m and a thermoplastic resin, the carbon and the resin being in a weight ratio from about 1:5 to 1:1; the composite characterized by 80--95% porosity by volume and a pore size diameter distribution from about 5 microns to about 200 microns.
