摘要：

The hydrogen evolution reaction was studied in 1M NaOH solution at 70-degrees-C on various PTFE-bonded electrode materials. Using steady-state galvanostatic measurements and ac. impedance spectroscopy, the electrode properties and kinetic parameters were determined. It was found that the a.c. behavior could be described by a constant phase element model and that the hydrogen evolution reaction proceeds via the Volmer-Heyrovsky mechanism. No catalytic effect of PTFE was found. The observed changes in performance could be explained by changes in the roughness of the electrode materials.
