Title:
FUEL CELL SYSTEM, AND INSUFFICIENT HUMIDIFICATION DETERMINATION METHOD OF FUEL CELL STACK
Document Type and Number:
Japanese Patent JP2007227160
Kind Code:
A
Abstract:
To provide a fuel cell system capable of estimating an insufficient humidification state of a fuel cell stack without installing an additional measuring instrument.
This fuel cell system is characterized by including: a droplet separation/recovery device 7 for recovering steam in an anode exhaust gas; a water level measuring device 8 for measuring the water level in the droplet separation/recovery device; a water level percentage change calculation part 16 for calculating water level percentage change; and an insufficient humidification determination part 17 for predicting that the fuel cell stack lacks humidification when the water level percentage change is below a determination value P.
