Management of a fuel cell system to feed a superconducting coil

Résumé

The fuel cell and the superconductor coil are electrical devices that give us a big number of expectations in the applied research domain. We know that the fuel cell is used as an alternative power supply that produces electrical energy from hydrogen and oxygen redox reaction. This is a clean power source that produces only water as waste. Whereas the fuel cell can produce important currents of a few hundred Amps in a dedicated working zone, the voltage produced is too small and needs to be conditioned by power electronics to make it suitable for use. That increases their cost and limits his mass production. In addition, the superconducting coils are used to produce strong magnetic fields, with less energy, at cryogenic temperature, e.g. the temperature of liquid Helium. Their main application is in the Magnetic Resonance Imaging (MRI) devices or in embedded systems. In order to create these magnetic fields, the superconducting coils require special kinds of power supply capable to provide high current at low voltage. Usually, these power supplies generate a non-negligible harmonic. Hence we have found a solution that can give a response to these problems. We are working on a system that uses a fuel cell as autonomous power supply for superconducting systems. The fuel cell can replace a high-current power supply and it fits perfectly as an alternative power supply for these systems, with the benefit of zero harmonic pollution. In this paper, we are working on a model for a set of a fuel cell and a superconducting coil. We also propose solutions to connect these two devices and to ensure the proper energy management.
