Abstract
Official abstract text for this publication.
Embodiments of the present anhydrous fuel cell electrodes comprise an anhydrous catalyst layer and a gas diffusion layer, wherein the anhydrous catalyst layer comprises at least one catalyst, about 5 mg/cm 2 to about 100 mg/cm 2 of phosphoric acid added as a catalyzing reagent during formation of the catalyst layer, and a binder comprising at least one triazole modified polymer, wherein the triazole modified polymer comprises a polysiloxane backbone and a triazole substituent.
First claim
Opening claim text (preview).
What is claimed is: 1. An anhydrous fuel cell electrode comprising an anhydrous catalyst layer and a gas diffusion layer, wherein the anhydrous catalyst layer comprises: at least one catalyst, about 5 mg/cm 2 to about 100 mg/cm 2 of phosphoric acid added as a sol-gel reaction catalyzing reagent during formation of the catalyst layer, and a binder comprising at least one triazole modified polymer, wherein the triazole modified polymer comprises a polysiloxane backbone and a t…
