The Kirk cell is an electrochemical device which basically resembles an electrochemical safety switch. Its function is to shunt hazardous voltages to ground in installations which, for reasons of corrosion protection, may not be grounded via metal conductors. The cell has a low resistance to the passage of AC current while blocking DC current. The Kirk cell consists of multiple pairs of stainless steel plates which are immersed in a 30% potassium hydroxide electrolyte solution.
