Abstract
A membrane electrode assembly includes an anode; a cathode; a membrane disposed between the anode and the cathode; and an extended catalyzed layer between the membrane and at least one electrode of the anode and the cathode. The extended catalyzed layer includes catalyst particles embedded in membrane material and preferably includes a first plurality of particles which are electrically connected to the at least one electrode. The extended catalyzed layer may further preferably have a second plurality of particles which are electrically disconnected from the at least one electrode.
