Saraiva Rocha da Silva, Fernando [UCL] de Radiguès de Chennevières, Quentin [UCL] Thunis, Grégoire [UCL] Proost, Joris [UCL]

The application of pulses is a promising method to enhance the efficiency of water electrolysis. In this review, we first present a historical overview with several seminal references on the topic. Then, we give an overview of the last researches. Possible reasons for the efficiency improvement are outlined, including an increase in reactant concentration at the electrode surface, the improvement of bubble detachment from the electrode, and the perturbation of the electrical double layer.
