Abstract
A compression apparatus includes an electrolyte membrane, an anode on a principal surface of the electrolyte membrane, a cathode on another principal surface of the electrolyte membrane, an anode separator on the anode, a cathode separator on the cathode, and a voltage applicator. Upon the voltage applicator applying a voltage, protons are extracted from an anode fluid fed to the anode to move to the cathode through the electrolyte membrane and compressed hydrogen is produced. The anode separator has a fluid channel, a manifold hole, and a communicating path which are formed in an anode-side principal surface. The compression apparatus includes a face seal disposed on an outer periphery of a region of the anode-side principal surface of the anode separator which faces the anode. The face seal has a three-layer structure including a metal sheet and a pair of elastic sheets.
