Abstract
A method of manufacturing a membrane electrode assembly for hydrogen fuel cells includes mixing an electrode binder with a catalyst, followed by dispersing and thermal treatment, to prepare an electrode slurry, coating release paper with the electrode slurry to produce an electrode, and bonding the release paper-coated electrode to an electrolyte membrane, followed by thermal treatment, to perform electrode-membrane bonding.
