The invention is relative to a membrane-electrode assembly for fuel cells comprising a state of the art ion-exchange polymeric membrane and by state of the art gas diffusion electrodes, whose electrochemical properties are modified , through the addition of a hydrophilic component localised in correspondence of one or both the electrodic interfaces and/or one or both the external surfaces of , the membrane. The such modified membrane-electrode assembly is characterised by high protonic conductivity and high efficiency even in the presence of small quantities of carbon monoxide or of other contaminants , contained in the fuel even at temperatures as low as 100°C, being also suitable …

Why it's free to use
- Filed October 25, 2001 and granted March 8, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 25, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 25, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
