ABSTRACT:
During operation of a fuel cell stack, electrolyte within individual fuel cells migrates between the cathode side and the anode side, and across the separator plate between the cathode side and the anode side electrolyte reservoir plate of a second cell. An electrochemical sensor comprised of wires, a sheath, and a porous conduit having a pore size distribution which is similar to that of the electrolyte reservoir plate in which the electrochemical sensor is located, is capable of determining the electrolyte content during fuel cell operation by measuring the electrical resistance between the wires. The conduit wicks electrolyte into its pores to a content similar to that of the electrolyte reservoir plate. This electrolyte establishes electrical contact between the wires such that the measure of the electrical resistance between the wires is related to the electrolyte content of the electrolyte reservoir plate.
