Hi Dear all
I am Using carbon cloths as a cathod in MFC. For loading catalyst Pt/C on carbon cloth , generally will use Nafion perfluorinated ion exchange as binding.
As you know Nafion perfluorinated ion exchange resin is very costly. So what can we use instead Nafion solution for preparing ink catalyst?
Thanks a lot
FuMA-Tech sells a PFSA and non-PFSA-based ionomer (and related membranes), http://www.fumatech.com/EN/Products/fumion/ both at reduced cost to Nafion - hydrocarbons may help you out in many ways, but I discuss some of the issues with the high-bp solvent + give links to research to mitigate these in this post:

There are more MFC-related resources in this post: https://www.researchgate.net/post/What_can_I_use_as_an_alternative_to_Nafion_in_MFC_cathode
I've done a ridiculous amount of spray-coating and experimented different cell constructions, so feel free to write me if you have questions.
Cheers,
Ben
