Description

<p>Direct local current and temperature measurements were performed in a planar solid oxide electrolysis cell (SOEC) by segmenting the anode (oxygen electrode) to measure the actual spatial current and temperature distributions for high temperature steam electrolysis along the cathode (hydrogen electrode) flow channels. Under voltage control, the currents and temperatures in the upstream, midstream, and downstream segments along the reactant vapor flow were successfully measured.</p>
