Abstract
An electrochemical cell apparatus is disclosed. The electrochemical cell apparatus includes a membrane-electrode assembly (MEA) having a membrane with a first side and a second side opposite the first side, a first electrode in contact with the first side, and a second electrode in contact with the second side. The apparatus further includes a flow field member and a protector member having a boundary partially defined by a first surface facing toward a center of the MEA. The second electrode has a boundary partially defined by a second surface facing away from the center of the MEA. A first distance from the center of the MEA to the first surface is greater than a correspondingly oriented second distance from the center of the MEA to the second surface, thereby defining a gap between the first surface and the second surface.
