Estimation of hydrogen consumption for proton-exchange membrane fuel cells systems

In this paper the fuel consumption of the Fuel Cell (FC) Systems using Fueling Optimization (FO) Strategies based on the Power Tracking Control (PTC) is reviewed. The objective is to find for each PTC-FO strategy a linear relationship between the fuel consumption and load. Finally, a generic linear relationship has been proposed for all PCT-FO strategies to estimate the fuel consumption within the allowable errors. This feature implemented on board the FC vehicle will help the driver to choose the preferred hydrogen filling station and also available on the driving route, given the fuel left in the tank.
