Abstract

An electrolyzer system comprises a stack of one or more electrolyzer cells, each electrolyzer cell comprising first and second half cells respectively comprising first and second electrodes and a separator between the first half cell and the second half cell, wherein a current is applied between the first and second electrodes. The system further comprises first and second electrolyte feed streams for respectively feeding a first electrolyte solution at a first inlet temperature to the first half cells and a second electrolyte solution at a second inlet temperature to the second half cells, first and second electrolyte outlet streams for respectively withdrawing the first and second electrolyte solutions from the first half cells and second half cells, and a temperature control apparatus to control the first inlet temperature at a first specified temperature and to control the second inlet temperature at a second specified temperature.
