Abstract
A high-pressure hydrogen producing apparatus includes a cell device and a piston member. The piston member is to apply a pressing force to the cell device from an end of the piston member in a stacking direction in which unit cells are stacked. The piston member is provided with a first hydrogen passage, at least one second hydrogen passage, and a hydrogen lead-out passage. The first hydrogen passage and the second hydrogen passage are spaced at substantially equal angular intervals on a virtual circle centered on a center of an end face of the piston member.
