Title:

METHOD FOR LOAD FOLLOW-UP OPERATION OF FUEL CELL SYSTEM

Document Type and Number:

WIPO Patent Application WO/2011/001909

Kind Code:

A1

Abstract:

Disclosed is a method for load follow-up operation of a fuel cell system enabling reliable reforming and prevention of flow path closure and anode deterioration. Functions F=f(P) and P=f-1(F) of the electric output P and the fuel flow rate F required to output P are defined in advance. A reforming catalyst layer temperature Tj and a fuel flow rate Gj at which the fuel can be reformed at the reforming catalyst temperature Tj are set. If Gj corresponding to the highest Tj equal to or lower than the catalyst layer measured temperature T is FR and if FRPM, (2) is performed. (1) If f(PD)≤FR, the output is set at PD, and the fuel flow rate is set at f(PD); and if f(PD)>FR, the output is set at the maximum value of P lower than PD and computed using P= f-1(FR), and the fuel flow rate is set at FR. (2) If f(PM)≤FR, the output is set at PM, and the fuel flow rate is set at f(PM); and if f(PM)>FR, the output is set at the maximum value of P computed using P=f-1(FR), and the fuel flow rate is set at FR.
