Hydrogen evolution reaction (HER) was studied on amorphous Co-P(x), Ni-P(x) and Fe-Ni-P(x) electrodes, prepared by an electrolytic deposition. The activities of Ni- and Co-P(x) electrodes prepared at room temperature are nearly equivalent, those of Fe-Ni-P(x) are somewhat lower. Alloys prepared by the electrodeposition at room temperature are very active for the HER, while those prepared at elevated temperatures 80-90 degrees C are less active. It has been proved that the high activity of Me-P(x) electrodes is caused by dissolved hydrogen in the amorphous layer in the course of the electrodeposition.
