Abstract

A method for determining a flow of a gas through an injector and a flow of a gas through a valve in a fuel cell system. The method includes determining an injector flow estimation for the gas flowing through the injector and determining a valve flow estimation for the gas flowing through the valve. The method also includes calculating an error that is a difference between the injector flow estimation and the valve flow estimation and adjusting the flow of the gas through the valve based on the error.
