Title:
FUEL CELL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2007/142246
Kind Code:
A1
Abstract:
A basic injection time of an injector (35) is obtained from an FC current detected in
step S1. The basic injection time based on the FC current is multiplied by a predetermined
correction coefficient K for correction (learning) and what is obtained by this
is re-defined as the basic injection time so as to obtain an injection time feed
forward term (F/F term) to be obtained finally (step S5). The correction coefficient
K is set by obtaining a flow rate characteristic per unit drive time of the injector
(35) according to the relationship between a total drive time Tinj and a total
injection quantity Q of the injector (35) until an FC entrance pressure at the
anode side of a fuel cell (10) applied upon system start reaches a predetermined
target pressure. The correction coefficient K is updated upon each system start.
