A review on synthesis and characterization of solid acid materials for fuel cell applications

Electrospun CNF Supported Ceramics as Electrochemical Catalysts for Water Splitting and Fuel Cell: A Review

“…The basic novelty in designing an electrocatalyst lies in developing unique architecture and active surface sites which play an important role in enhancing the electron transfers ability of the catalyst. The electrocatalyst can be of different forms, like that of a photoelectrocatalyst, a solution phase electrocatalyst, surface electrocatalyst, and many others [60][61][62][63][64]. Such electrocatalysts should be cheap, stable, selective and abundant enough to be used in large scale applications.…”

Facile and scalable synthesis of sub-micrometer electrolyte particles for solid acid fuel cells

“…The conventional synthesis of CsH 2 PO 4 for SAFCs is based on the precipitation from an aqueous solution of the precursors by the addition of a non-solvent, usually methanol. 1,2 The addition of the methanol gradually decreases the solubility of CsH 2 PO 4 , leading to precipitation. While the precursors are soluble in alcohols, the product is not.…”

“…240 C the electrolyte is in the superprotonic phase with high proton conductivity. 1,2 The solid-state electrolyte and the intermediate operating temperature lead to a number of advantages, such as resistance to catalyst poisoning, cost-effective engineering materials, ease of handling, and simple water management. 3 Nevertheless, the loading of platinum as electrocatalyst in SAFCs still has to be reduced to allow broad application.…”

A novel thermomechanically stable LaF3CsH5(PO4)2 composite electrolyte with high proton conductivity at elevated temperatures over 150 °C

“…Among all solid acid electrolytes, cesium dihydrogen phosphate (CsH 2 PO 4 , abbreviated as CDP) was studied extensively because of its great ther-mal stability with melting temperature up to ca. 345 °C [25,26] and high proton conductivity of 10 −2 S cm −1 level at temperatures above 230 °C, recognized as the super-protonic transition temperature from a low-conducting phase (monoclinic phase) to a superprotonic phase (cubic phase) [12,[26][27][28][29][30] .…”
