COOLING DEVICE FOR FUEL CELL AND COOLING METHOD

Title:

COOLING DEVICE FOR FUEL CELL AND COOLING METHOD

Document Type and Number:

WIPO Patent Application WO/2005/086268

Kind Code:

A1

Abstract:

A cooling device for a fuel cell capable of keeping the conductivity of a cooling liquid within a specified range even when a quick load change occurs. The cooling device for a fuel cell (10) is characterized by being constituted so as to be able to control, based on the correlation between refrigerant-temperature-related parameters and the conductivity of that refrigerant, refrigerant-temperature-related parameters (T_H, T_L) so that a conductivity (S) at a target set temperature is kept within a target conductivity range (S_max - S_min). Since a conductivity is feed-forward-controlled based on the correlation between refrigerant-temperature-related parameters and the conductivity of that refrigerant, the conductivity of the refrigerant can be positively kept within a target range even when a conductivity with a poor responsiveness is controlled.
