Claim 0:
1. A system comprising:
a coolant loop acting as a conduit for a coolant for cooling a fuel cell, the coolant loop having a first portion having a terminal end with an opening and a second portion fluidly connected to the first portion;
an ion exchanger configured to deionize the coolant;
a conductivity sensor configured to output an electrical signal indicating a conductivity of the coolant, the conductivity sensor at least partially disposed within the opening; and
a processor in communication with the conductivity sensor and a memory, the memory having a conductivity monitoring module 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.
