Virtual fuel cell system

Abstract

The purpose of this project was to build a computer model able of running virtual simulations and emulations of fuel cell (FC) systems. This was aimed at the transport market and modern built environment. The project incorporates the novel use of hardware, firmware and software operating in real-time to simulate real applications in vehicles and buildings. A fuel cell system is a complex assembly of components, all of which are all critical to its performance. To get the best from the system each of the system components must be optimized. Current practice uses prototyping of real hardware and testing. Such work is specific to single FC suppliers and is based on off-line modeling or real-time analysis against monitored loads. The innovation in this project is in integrating the optimization step into the development of the complete system. The technical breakthrough is shown through closing the development gap between concept and final design by creating a real-time simulation and emulation process to develop optimum FC systems for the transport and built environment markets. The virtual fuel cell can be operated safely outside the limits that it would normally encounter for given criteria. This extends the know-how beyond conventional testing. The time consuming and costly setting up of hardware tests with an actual fuel cell is therefore not required. This project outcome gives the new ability to design and engineer optimized FC systems without the risk of component / subsystem redundancy. It relinquishes the requirement for a hydrogen source, cooling; pumps, water etc. and gives rise to a completely safe test environment.
