To provide an earthwork machine which achieves high insulation resistance while equipped with a fuel battery.SOLUTION: An earthwork machine includes a vehicle body, a fuel battery, a housing, and a refrigerant pipe. The housing contains the fuel battery and is electrically connected to the vehicle body. The refrigerant pipe penetrates through the housing and allows a refrigerant to flow from the outside of the housing to the fuel battery. The refrigerant pipe is electrically insulated from the housing. The refrigerant and the vehicle body are electrically connected at the outside of the housing.SELECTED DRAWING: Figure 2
【課題】燃料電池を搭載しつつ、高い絶縁抵抗を実現する。【解決手段】土工機械は、車体と、燃料電池と、筐体と、冷媒配管とを備える。筐体は、燃料電池を格納し、車体に電気的に接続される。冷媒配管は、筐体を貫通して筐体の外部から燃料電池へ冷媒を流す。冷媒配管は、筐体と電気的に絶縁され、筐体の外部で冷媒と車体とが電気的に接続されるように構成される。【選択図】図2
