ELECTROCHEMICAL CELL HAVING PROTECTION AGAINST CREEP

摘要

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.
