This invention provides a low-temperature start-up
system for a
proton exchange membrane fuel
cell, belonging to the field of fuel
cell technology. It solves the problems of excessively long
heating time, uneven heating, and limited fuel
cell output power during low-temperature start-up in existing technologies. The
system includes a
hysteresis heating component, a power
lithium battery, a fuel cell, a DC-
DC converter, a DC-AC converter, a frequency converter, and a first
solenoid valve. The
hysteresis heating component includes a magnetic conductor and an energized coil wound around the magnetic conductor. One end of the magnetic conductor has a first magnetic conductor opening for inserting the power
lithium battery, and the other end has a second magnetic conductor opening for inserting the fuel cell. The first
solenoid valve, the energized coil, and the frequency converter are connected sequentially to form a
hysteresis effect generation circuit. The fuel cell supplies power to the hysteresis effect generation circuit after sequentially passing through the DC-
DC converter and the DC-AC converter. This
system generates an alternating
magnetic field through the hysteresis heating component to heat the fuel cell and the power
lithium battery.
