Compositions and methods for the manufacture of electrodes for fuel cells. The compositions and methods are particularly useful for the manufacture of anodes and cathodes for proton exchange membrane fuel cells, particularly direct methanol fuel cells. The methods can utilize direct-write tools to deposit ink compositions and form functional layers of a membrane electrode assembly having controlled properties and enhanced performance.

L'invention concerne des compositions et des procédés permettant de produire des électrodes de piles à combustible. Ces compositions et ces procédés conviennent particulièrement pour la production d'anodes et de cathodes destinées à des piles à combustible à membrane échangeuse de protons, en particulier les piles à combustible au méthanol. Ces procédés peuvent comprendre l'utilisation d'instruments d'inscription directe pour déposer des compositions d'encre et former les couches fonctionnelles d'un assemblage électrode-membrane présentant des propriétés sélectionnées et une performance améliorée.
