To give a simplified example. Assume you get 80% efficiency at 1.5 V cell voltage. Double the voltage and get e.g doubled current and double gas yield. Efficiency however drops to 40%. Because you apply fourfold input power but get only doubled gas production.
Oh I see now, yes you right 100%
thanks for bringing me from darkness to the light
how somebody can miss that? ashamed of myself
