A fuel cell system includes fuel cells, a circulation channel of a coolant to cool the fuel cells, and an ion exchange resin provided on the circulation channel to maintain electrical conductivity of the coolant. The coolant contains an additive. The ion exchange resin is prepared so that adsorption of the additive on the ion exchange resin is in a saturated state. A fuel-cell vehicle includes the fuel cell system.

A heating medium composition for suppressing deterioration of both a metal piping and a synthetic resin piping. The heating medium composition contains an antifreeze ingredient, water, a corrosion inhibitor, and a surfactant. The corrosion inhibitor includes a triazole compound, and the surfactant includes an anionic surfactant. A bag in a feeder provided in a given position along a circulation piping is filled with an oxidation inhibitor. By flowing a heating medium composition through the feeder, the oxidation inhibitor is gradually dissolved in the heating medium composition.
