  "textContent": "A High Temperature Proton Exchange Membrane (HT-PEM) fuel cell includes a Proton Exchange Membrane (PEM); an anode catalyst layer on one surface of the PEM, and a cathode catalyst layer on the opposite surface of the PEM; Gas Diffusion Layers (GDLs) on outside surfaces of the anode and the cathode layers; and Bipolar Plates (BPPs) on outside surfaces of the GDLs. One or more contacting surfaces of the Membrane Exchange Assembly (MEA) subcomponents are coated, at least in part, with an electrically conductive polymer composite material that softens at or below the operating temperature of the HT-PEM. Also disclosed is a fuel cell bipolar plate (BPP) that includes a plurality of gaseous media coolant flow channels which have deflection barriers configured to cause the gaseous media coolant to divide and flow horizontally around a deflection barrier in a direction of an adjacent gaseous media coolant flow channel.",
