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.

Electrochemical cell apparatus

An electrochemical cell having a membrane electrode assembly (MEA), and a gas diffusion layer (GDL) disposed proximate a side of the MEA with an edge of the GDL disposed inboard of an edge of the MEA is disclosed. A sealing member is disposed proximate the edge of the GDL and extends outward toward the edge of the MEA, thereby defining a discontinuity between the GDL and the sealing member. A protector member is disposed between the MEA and the GDL such that the protector member traverses the discontinuity.
