This paper deals with control of the fuel cell stack with DC/DC boost converter connected at its output. Feed-forward and feedback controllers of the fuel cell system are designed independently of the boost converter. The voltage control of the boost converter is realized through its input voltage, using fuel cell stack as an actuator, while the PWM duty cycle is left constant. The boost converter...
A compressor-based air supply system in a fuel cell is susceptible to saturation during fast transients in load. Aggressive control of the air compressor may result in compressor surge or choke, disrupt the flow of air into the cathode of a fuel cell stack, and negatively impact the fuel cell power generation. Low partial oxygen pressure in the cathode caused by rapid increase in load may also damage...
In this work a nonlinear dynamical model of a fuel cell stack is developed by means of artificial neural networks. The model presented is a black-box model, based on a set of easily measurable exogenous inputs like pressures and temperatures at the stack and is able to predict the output voltage of the fuel cell stack. The model obtained is being exploited as a component of complex control systems...
