Super–protonic conductors for solid acid fuel cells (SAFCs): a review

Abstract

Fuel cell holds the promise of being environmentally friendly and becomes one of the alternatives for renewable energy. Solid acids have super-protonic behavior which allows them to become conductors. It can function at high temperatures. Hydration, on the other hand, may be used to improve the performance of the solid acid. Moreover, the conductivity, stability, and crystal structure of the solid acid compounds of the fuel cell are all influenced by the size of the electrolyte membrane. Very few works have been done on solid acid fuel cells which are still under investigation to make it one viable as well as a reliable alternative to clean, renewable energy. In general, this work will provide an overview of the variables or characteristics that affect the technical effectiveness and performance of the unique super-protonic conductors for solid acid fuel cells.

Ultra-Low Loading of Iron Oxide and Platinum on CVD-Graphene Composites as Effective Electrode Catalysts for Solid Acid Fuel Cells

“…In comparison to combustion engines, fuel cells are a more environmentally friendly alternative to fossil fuel-based energy sources, converting chemical energy directly and continuously into electrical energy, and vice versa, with high efficiency and low/or no pollutant emissions [1][2][3][4][5][6]. An intermediate temperature fuel cell, which is based on a new class of electrolytes called solid acid caesium dihydrogen phosphate (CsH 2 PO 4 , CDP), is cited as a promising solution to the energy crisis [7][8][9][10][11][12][13][14]. The unique characteristics of the CDP electrolyte present several challenges for the optimization of the solid acid fuel cell (SAFC), specifically in relation to the cathode microstructure.…”
