Abstract

Electrochemical actuators are promising candidates for implementation in various microfluidic systems, but they suffer from a very long response time due to slow gas recombination. Water electrolysis performed by short voltage pulses of alternating polarity (AP) reduces the response time by several orders of magnitude. This process, however, results in a fast degradation of electrodes. It is important to find a material, which is able to withstand the AP operation without significant degradation. In this work the electrodes made of six metals are fabricated and tested. The current flowing through the cell, the threshold voltage for the explosive operation, and the wear of the electrodes are analyzed and compared.
