26 Million current cycles in the sub-second scale for fast dynamic electrolysis operation with a 30 layer electrolyte-supported cell stack

Fast dynamic operation in the sub-second scale is demonstrated for high-temperature steam electrolyzers. The current was switched between thermoneutral voltage and OCV (i.e., two operation points without the need for thermal management) using pulse width modulation with a 200 ms...
