Last in the Manifold

CO₂ starvation and ethylene loss along a ten-cell zero-gap electrolyser stack

A research poster from the School of Settled Matters runs a ten-cell zero-gap CO₂ electrolyser stack from one Z-type inlet manifold at a single shared current and samples each cell's outlet separately. At 1.5× stoichiometric feed the tenth cell receives 61% of the first cell's CO₂ and its ethylene Faradaic efficiency falls from 43% to 18%, the decline beginning at cell 7; exchanged cathodes take on the selectivity of their new position, and the spread closes to 5 points at 4× feed.
