Validation of developed materials in a short-stack PEMFC

In this deliverable, a description of the scale-up procedure for radical scavenger and recast membranes is reported. The radical scavenger procedure is based on a scalable method of the sulphite complex route allowing to increase tenfold the amount of scavenger produced in the D3.1. Similarly, a scale-up procedure for both bare and composite membranes development was carried out. This procedure based on Doctor-blade casting technique, allows to obtain membranes reaching dimensions of 12X30cm suitable for application in short stack. The preparative procedure was properly modified starting from those reported in the D3.1.
