Resumen de: GB2633564A
A method of changing the electrolytic conversion rate within at least one electrolyser cell 10 stack 12 of an electrolyser system (figure 1, 20) is described. The stack 12 has a fluid inlet 114, fluid outlet 116 and a power control system 108. The power control system 108 is used to change the voltage, via a voltage interface 100 across the electrolyser cell stack 12, allowing the fluid outlet temperature 104 to change in response to the voltage change, setting an inlet temperature 106 to substantially match the new outlet temperature, and then allowing the voltage to revert to a substantially thermoneutral value. The electrolyser cell stack 12 is thus operating at a changed stack temperature and changed electrolytic conversion rate. A processor 110 and memory circuit 112 can also be provided for storing information such as preset current, voltage or power delivery changes. The current method may lead to a galvanostatic thermoneutral (GTN) strategy for electrolyzer stack control.
