HYDROGEN REFINING PRESSURE-BOOSTING DEVICE

摘要

Provided is a hydrogen purification/compression apparatus that endures even a high-pressure environment. Provided is a hydrogen purification/compression apparatus 3 that produces, from hydrogen-containing gas, purified hydrogen gas having a higher pressure and a higher purity than the pressure and purity of the hydrogen-containing gas. The hydrogen purification/compression apparatus 3 includes multiple stacked cell structures 8 and a pressing structure (6, 7, 9, 10) that applies a clamping stress in the stacking direction of the cell structure 8. In the hydrogen purification/compression apparatus 3, a passage surface 30b of a cathode-side separator has a size such that the passage surface falls within a passage surface 20b of an anode-side separator in a plane parallel with a polymer electrolyte membrane 40.
