Resumen de: EP4567199A1
A construction machine includes a machine body, an electrically driven motor as a power source, a fuel cell that generates electric power to be supplied to the electrically driven motor, a battery that stores the electric power generated by the fuel cell, an inclination angle sensor that senses an inclination of the machine body, and a controller, in which the controller switches supplying of the electric power to the electrically driven motor from the fuel cell to the battery when a sensing result from the inclination angle sensor is equal to or larger than a predetermined inclination angle threshold. With this arrangement, even when the machine body is inclined, the water generated in the process of generating electric power by the fuel cell is prevented from being left undrained.
