[交流] 【求助】about commercial neutral separation membranes for fuel cells

Can some friends recommend the commercial neutral separation membranes for fuel cell applications?

The requirements are:
1) Separation membranes (for Polymer electrolyte membrane fuel cells)
2) thickness: between 30 micrometer to 200 micrometer
3) commercially available
4) has some pores so that the membrane can be used as matrix for absorbing ionic liquids
5) can stand temperatures up to 180 degrees C.


Nafion or PBI are not suitable, because it will react with ionic liquids...


Thanks.

这么大孔径?自己弄点PVDF/PES/PSF,溶解到NMP/DMSO/DMF/DMAc中去,通过相反转法成膜。很容易。


thanks.
it is not the pore size. It is the thickness of the commercial membrane.
