Title: Ink for producing catalyst layers
Inventor: BEHL WALTER
IPC: C25B9/23
Filed: 2006-03-25
Abstract: The invention relates to an ink for producing catalyst layers for electrochemical devices. The ink comprises catalyst material, ionomer material, water and at least one organic solvent. The organic solvent belongs to the class of tertiary alcohol~s and/or the class of aliphatic diketones and bears functional groups which are stable to oxidative degradation in the ink.
