Differential pressure electrolysis cell and differential pressure electrolysis stack

A differential pressure electrolysis cell configured to electrolyze an electrolysis fluid supplied to a first electrode catalyst layer to generate a product gas in a second electrode catalyst layer, the product gas having a higher pressure than the electrolysis fluid,

• the differential pressure electrolysis cell comprising:
• a membrane electrode assembly including an electrolyte membrane, the first electrode catalyst layer and the second electrode catalyst layer, the first electrode catalyst layer and the second electrode catalyst layer being joined to opposite sides of the electrolyte membrane;
• a metal separator arranged above the second electrode catalyst layer;
• a conductive sheet disposed on a current collector positioned between the metal separator and the second electrode catalyst layer;
• a spring member made of metal, in contact with the metal separator and the conductive sheet, and configured to press the conductive sheet downward;
• and
• a capturing member provided on an outer circumferential portion of the conductive sheet and configured to capture cations.
