Fuel cell facility for supplying power to portable electric machines links up their power circuits with those of fuel cells connected to fuel cell controllers with sensors and starter batteries.

摘要

A power regulator (8) separates a fuel cell (2) and a battery (6) from electric motors (26a,26b) in a portable machine (30) before reaching an operating state in the fuel cell. After an operating state is detected by sensors (4a-4c), the power regulator is disconnected from a fuel cell controller (3) so that electric power generated by the fuel cell passes to a portable machine.
