The invention discloses a hydrogen fuel aircraft. The hydrogen fuel aircraft comprises a liquid hydrogen fuel storage tank, a liquid hydrogen conveying pipe, wings and an aircraft body; the liquid hydrogen fuel storage tank is located in a lower-layer space of the aircraft body and comprises multiple storage tank bodies, and the storage tank bodies are located on the front portion, the middle portion, and the back portion of the aircraft body; the liquid hydrogen conveying pipe comprises a first pipe and a second pipe; the first pipe comprises multiple pipe bodies, and the pipe bodies of the first pipe are used for being communicated with every two adjacent storage tank bodies; an inlet of the second pipe is connected with the liquid hydrogen fuel storage tank on the middle portion of theaircraft body; an outlet of the second pipe is connected with a fuel inlet of an engine, and pipe bodies of the second pipe are fixed to the front edges of the wings. According to the hydrogen fuel aircraft, liquid hydrogen is used as fuel, and the aircraft causes no pollution, saves energy and reduces emission. Through reasonable arrangement of the liquid hydrogen conveying pipe, the temperatureof the front edges of the wings is lowered by using heat absorption in the liquid hydrogen gasification process, flow transition of the surfaces of the wings is delayed, then the resistance to the aircraft is reduced, and the performance of the aircraft and the economy are improved.
