And the article contained the following:
The electrode ionomer is a key factor that significantly affects the catalyst layer morphol. and fuel cell performance. Herein, sulfonated poly(arylene ether sulfone)-based electrode ionomers with polymers of various mol. weights and alc./water mixtures were prepared, and those comprising the alc./water mixture showed a higher performance than the ones prepared using higher boiling solvents, such as dimethylacetamide; this is owing to the formation of the uniformly dispersed ionomer catalyst layer. The relation between ionomer mol. weight for the same polymer structure and the sulfonation degree was investigated. Because the chain length of polymer varies with mol. weight and chain entanglement degree, its mol. weight affects the electrode morphol. As the ionomer covered the catalyst, the agglomerates formed were of different morphologies according to their mol. weight, which could be deduced indirectly through dynamic light scattering and SEM. Addnl., the fuel cell performance was confirmed in the current-voltage curve. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Recommanded Product: 80-07-9
