Ionomer used for fuel cell and method for producing the same |
| abstract |
Reaction products of monomers containing phthalazinone and phenolic groups with at least one sulfonated aromatic compound. Phthalazinone and monomers containing phenolic groups are used to react with the sulfonated aromatics to produce ionomers with surprisingly desirable properties. In one embodiment, the novel ionomer is a sulfonated poly (phthalazinone ether ketone) (hereinafter PPEK). In another aspect, the novel ionomer is a sulfonated poly (phthalazinone ether sulfone) (hereinafter referred to as SPPES). In yet another embodiment, the novel ionomer is another sulfonated aromatic polymer compound. The present invention further forms these polymers into membranes and can be used in polymer electrolyte membranes (PEMFCs) for fuel cells, especially for direct methanol fuel cells (DMFCs). The polymers of the present invention can be manufactured in the form of a membrane, which can subsequently be dissolved in a solution and dipped into a porous substrate to form a composite polymer electrolyte membrane having good properties. |
