In the near future, the mechanical systems using hydrogen energy such as a fuel cell vehicle will be widely used. From the point of safty measure, the hydrogen sensors are the necessities. In this paper, a new acoustic method of detecting hydrogen leakage is proposed. This acoustic method is effective in wide space such as a basement parking lot. Three-dimensional computer simulations of sound propagation using finite difference time domain FDTD method is carried out. A basic experiment using helium, instead of hydrogen is also carried out. The validity of the proposed method is shown from the results of simulation and experiment.
