RollPriCat – Production of graded catalyst layers in inkjet printing<\/h1>\n

MEAs for fuel cells: New roll-to-roll process applies catalyst ink directly to the membrane – from both sides.<\/p>\n<\/div>\n

In the recently completed “RollPriCat” project, the Fraunhofer Institute for Electronic Nano Systems (ENAS) and the ZBT have jointly developed a novel process for the production of MEAs<\/strong> for PEM fuel cells in which catalytically active ink<\/strong> is applied directly to the membrane<\/strong> – on both the anode and cathode sides.<\/p>\n

The aim of the project was to achieve a high activity of the cathode catalyst layer (CCL) with less platinum coating than before. This was to be ensured by a customised spatial structuring of the cathode catalyst layer using inkjet technology. <\/p>\n<\/div>\n <\/div>\n
