| 1. An electrochemical cell comprising:
a membrane electrode assembly (MEA);
a gas diffusion layer (GDL) disposed proximate a side of the MEA, an edge of the GDL disposed inboard of an edge of the MEA,
said GDL having a coined region on an edge;
a sealing member disposed proximate the edge of the GDL and extending outward toward the edge of the MEA, thereby defining
a discontinuity between the GDL and the sealing member; and
a protector member disposed between the MEA and the GDL in the coined region of the GDL, such that the protector member traverses
the discontinuity.
