✦ Synopsis

Steady-state and potentioatatic transient H, evolution studies on Teflon bonded Pt black, platinired Pt and Pt foil electrodes in 5N H,SO,, 25°C showed that teflon bonded electrodes gave * a higher performance than the other electrodes. The presence of the porous hydrophobic teflon network ensures that not all the electrolyte will be expelled from the pores of the electrode during the gas evolution process, thus ensuring greater utilization of the available Pt area.
