ALKALI FUEL CELL UNAFFECTED BY CARBONATATION

摘要

The invention relates to an alkali fuel cell comprising a solid stack consisting of a first electrode (2), a solid membrane (3) conducting hydroxide ions, and a second electrode (4), each electrode (2, 4) comprising an active layer (2a, 4a) that is in contact with the solid membrane (3). The material of the active layer (2a, 4a) of each electrode (2a, 4) comprises at least one catalytic element, an electronic conductive element, and an element conducting hydroxide ions. The element that conducts hydroxide ions is a styrenic polymer having a quaternary ammonium function, and a hydroxide ion OH- is associated with each quaternary ammonium function. One such alkali fuel cell is unaffected by carbonatation and maintains good electrochemical performances.
