Fuel cell throttle

Abstract:

The disclosed technology is generally directed to fuel cells. In one example of the technology, a fuel cell stack that includes an anode and a cathode causes a load to be driven. A control subsystem is measures at least one characteristic associated with the load, and to provide at least one control signal based, at least in part, on the at least one characteristic. An oxidizing agent input subsystem provides an oxidizing agent to the cathode of the fuel cell stack. A fuel input subsystem provides gaseous fuel to the anode of the fuel cell stack. The fuel input subsystem includes a fuel pump that is arranged to pump the gaseous fuel into the fuel input subsystem. A fuel-side high-speed valve adjusts mass flow of the gaseous fuel to the cathode of the fuel cell stack based on at least a first control signal of the at least one control signal.
