Fuel cell and portable device equipped with the same, and fuel cell operating method

摘要

A fuel cell includes a fuel cell main unit ( 101 ), a fuel holder ( 334 ) and a transforming section ( 335 ). The fuel cell main unit ( 101 ) includes a fuel electrode ( 102 ) and an oxidant electrode ( 108 ), and generates electric power based on supplying of organic liquid fuel ( 124 ) to the fuel electrode ( 102 ) and oxidant ( 126 ) to the oxidant electrode ( 108 ). The fuel holder ( 334 ) stores the organic liquid fuel ( 124 ) and supplies the organic liquid fuel ( 124 ) to the fuel electrode ( 102 ). The transforming section ( 335 ) transforms the organic liquid fuel ( 124 ) into vapor or mist ( 337 ). The fuel holder ( 334 ) supplies the vapor or the mist ( 337 ) to the fuel electrode ( 102 ).
