Abstract

The performance of a six-cell zero-gap electrolyser with an active area of 300 cm2 was analysed. The device featured a new design of flowplate that employed spot-welding in order to eliminate machining costs. Direct resistance measurements were made, and computer simulations performed to confirm the...
