Fuel cell control system for fuel cell comprising an ionic liquid containing electrolyte

摘要

A fuel cell control system of the present invention includes a fuel cell (10) using as the electrolyte (11) an ionic conductor containing a cation component, an anion component, and a polar substance; and a polar substance amount controller controlling an amount of the polar substance in the electrolyte (11) according to the operating condition of the fuel cell. The fuel cell control system can maintain high protonic conductance in all the ranges from the low-load operation range to the high-load operation range.
