FUEL CELL

摘要

A fuel cell comprising a fuel electrode and an oxygen electrode arranged oppositely to each other via a proton conductor. The fuel electrode and the oxygen electrode have carbon-nanotube-containing collectors that are high in strength and density. The collectors deliver their own excellent functions while being assisted by a good electronic conductivity specific to carbon nanotube itself. In addition, a collector containing carbon nanotube eliminates the need of paying attention to the mechanical strengths of a fue l electrode and an oxygen electrode to thereby be able to reduce these electrodes in thickness.
