The present invention discloses a process for the preparation of poly-benzimidazole (PBI) based membrane electrode assembly (MEA) with improved fuel cell performance and stability. It discloses a simple strategy to overcome the leaching of phosphoric acid (PA) from the membrane during fuel cell operation by an in-situ Current-Voltage (I-V) assisted doping of membrane with PA. The invention provides an improved method for the preparation of membrane electrode assembly (MEA) wherein said MEA possess high stability and improved fuel cell performance achieved by overcoming the leaching of phosphoric acid during cell operation.

PBI-based MEAs for high temperature Polymer Electrolyte Membrane Fuel Cell (PEMFC) were prepared by direct hot pressing of catalyst layer on Teflon sheets on to both sides of phosphoric acid doped PBI membrane (decal transfer). These MEAs show two times higher performance compared to the MEAs prepared by normal brush coating method on GDL at an operating temperature of 160&#xb0; C.
