Cs_0.86(NH₄)_1.14SO₄Te(OH)₆ supported by anodic alumina membranes (AAMs) has been characterized for the first time in H₂/O₂ fuel cell. The fabricated membrane electrode assemblies are able to produce peak power densities in the range 15–30 mW cm⁻² under mild conditions (room temperature, low humidity and low Pt loading) and show an increased durability with cycling with respect to previous results obtained with AAM-based fuel cell. The physico-chemical characterization of the electrolytes has been carried out through X-ray diffractometry, scanning electron microscopy and micro-raman analysis. An estimation of the composite membranes conductance under fuel cell operation has been carried out from I–V characteristics and EIS measurements at room temperature.
