MEMBRANE-ELECTRODE ASSEMBLY AND FUEL CELL COMPRISING THE SAME

A membrane-electrode assembly (10) is characterized by including an electrolytic membrane (11) having proton conductivity and a first electrode (12) jointed on the electrolytic membrane. The first electrode has a catalyst (121, 122) and a first ionomer (123) covering the catalyst and acting as a pro...

Beschreibung
Zusammenfassung:	A membrane-electrode assembly (10) is characterized by including an electrolytic membrane (11) having proton conductivity and a first electrode (12) jointed on the electrolytic membrane. The first electrode has a catalyst (121, 122) and a first ionomer (123) covering the catalyst and acting as a proton exchange group. A ratio of water-generation amount (mol/min) at rated output point of the membrane-electrode assembly / volume (cm 3 ) of the first ionomer in the first electrode is 1350 or larger.
