Catalyst layer optimization by surface tension control during ink formulation of membrane electrode assemblies in proton exchange membrane fuel cell

► We developed a compound stable over time to preparation of membrane electrode assemblies for proton exchange membrane fuel cell by sieve printing. ► We examine a mixture of solvents with low vapor pressure and high boiling point, and developed efficient catalyst and Nafion ionomers transportation at printing process. ► In this study the compound was characterized shown adequate proprieties to application on gas diffusions layer by sieve printing. ► The developed screen printing process using the compound is quick and reproductive reducing membrane electrode assemblies cost per quilowat.
