The level of electrical current produced by a fuel cell during rapid changes in the power demanded by a load, is clamped to the fuel cell's maximum rated current value in order to avoid damage to the fuel cell. When the current supplied to the load by the fuel cell overshoots the maximum rated current value, the fuel cell current is immediately reduced by increasing the fuel cell voltage.

Method for controlling fuel cell stack current

An alternative fuel vehicle having a fuel economy control module with associated logic that allows the vehicle to operate in a fuel economy mode based on a desired fuel economy preference. The fuel economy control logic is in electrical communication with a vehicle system controller (VSC) and may be integrally formed as a sub-module within the VSC. A fuel economy control switch controlled by the fuel economy control logic toggles between an on and an off position to enable or disable a fuel economy mode. A fuel economy control selector allows a user to select a desired fuel economy mode preference once the fuel economy control switch is on. The fuel economy mode selected represents a predefined desired fuel economy preference such as a distance per amount of fuel consumed, or alternatively, a percentage of a balance between a fuel economy operation and a fuel performance operation.
