HYDROGEN PRODUCTION SYSTEM FOR FUEL CELL, FUEL CELL SYSTEM, DEIONIZATION METHOD FOR HYDROCARBON FUEL, AND HYDROGEN PRODUCTION METHOD

摘要

This hydrogen production system for a fuel cell is provided with: a fuel supplying unit which supplies, to a later stage, a hydrocarbon fuel containing a sulfur compound and moisture having a conductivity of 0.05 to 500 µS/cm; a desulfurization unit which has a desulfurization catalyst for desulfurizing the hydrocarbon fuel; a hydrogen generating unit which generates hydrogen from the hydrocarbon fuel; and a deionization unit which is disposed between the fuel supplying unit and the desulfurization unit or between the desulfurization unit and the hydrogen generating unit and which brings the hydrocarbon fuel supplied from the fuel supplying unit or the hydrocarbon fuel that passed through the desulfurization unit into contact with a porous ion adsorbent.
