FUEL CELL AND METHOD OF USE TEEREOF

摘要

Fuel cell (500) comprising solid electrolyte membrane (114), fuel electrode (102) and oxidizer electrode (108) provided so as to have the solid electrolyte membrane (114) interposed therebetween, and fuel chamber (502) capable of feeding liquid fuel to the fuel electrode (102). Trapping agent (504) for capturing carbonate ions is introduced in the fuel chamber (502). The trapping agent (504) comprises metal cations and a retainer capable of retaining the metal cations within a given region. The metal cations couple with carbonate ions to thereby form carbonates and cause precipitation thereof, so that retention of carbon dioxide bubbles in the vicinity of fuel electrode (102) can be inhibited and feeding of fuel to the fuel electrode is not interfered with to thereby enable enhancing the power generating efficiency of the fuel cell (500).
