The aim is to take advantage of the low voltage and high DC
current free of ripples of the PEMFC that fit the criteria of the
power supplies used for the Superconducting Coils (SC). The
current ripple and current stability for these power supplies are
generally around 10 to 100 ppm [6], [7].
Therefore, these characteristics make suitable the devices for
working together. This opens a new and revolutionary use of
the PEMFC as a power supply for superconducting devices.
However, the need remains to use power electronics as an
apparatus able to protect the both systems, but this one is less
complex than the classic power electronics converters used.
