Fuel cell moisture amount estimation device and fuel cell system

摘要

The present invention provides a fuel cell moisture amount estimation device and a fuel cell system capable of accurately grasping a moisture amount in a cell plane. An apparatus for estimating the amount of water in a fuel cell takes into account water movement between an anode electrode and a cathode electrode through an electrolyte membrane, and a remaining amount of water in a reaction gas channel in a cell surface of a single cell. An estimation unit for estimating the distribution and the moisture content distribution of the electrolyte membrane; The fuel cell system controls the fuel cell to be in a predetermined moisture state based on the estimation result by the estimation unit.
