Abstract
Described are systems and methods for directly monitoring the conductivity of the coolant used to regulate the temperature of a fuel cell. The system includes a coolant loop that acts as a conduit for the coolant, an ion exchanger configured to deionize the coolant, and a conductivity sensor configured to output an electrical signal indicating a conductivity of the coolant. The system also includes a processor in communication with the conductivity sensor and a memory having instructions that, when executed by the processor, cause the processor to determine the conductivity of the coolant based on the electrical signal from the conductivity sensor and determine when the ion exchanger requires servicing based on the conductivity of the coolant.
