Journal ArticleDOI
Solid acids as fuel cell electrolytes
TL;DR: It is shown that a cell made of a CsHSO4 electrolyte membrane operating at 150–160 °C in a H2/O2 configuration exhibits promising electrochemical performances: open circuit voltages of 1.11 V and current densities of 44 mA cm-2 at short circuit.
Journal ArticleDOI
Solid acid proton conductors: from laboratory curiosities to fuel cell electrolytes
TL;DR: The result indicates that enhancing power output beyond the present levels will require improving cathode properties rather than further lowering the electrolyte thickness, and a discussion of the entropy of the superprotonic transition and the implications for proton transport is presented.
Journal ArticleDOI
A review on phosphate based, solid state, protonic conductors for intermediate temperature fuel cells.
TL;DR: In this review, the potential use of phosphate compounds as electrolytes for intermediate temperature fuel cells is summarized and various examples on ammonium polyphosphate, pyroph phosphate, cesium phosphate and other phosphate based electrolytes are presented and their preparation methods, conduction mechanism and conductivity values are demonstrated.
Journal ArticleDOI
Instability of sulfate and selenate solid acids in fuel cell environments
TL;DR: In this paper, the chemical and thermal stability of several solid acid compounds under fuel cell operating conditions has been investigated, primarily by thermogravimetric methods, and the overall decomposition process can be expressed as 2CsHSO_4 → Cs_2SO_4 + H 2O + SO_3 with Cs 2S_2O_7 appearing as an intermediate byproduct at slow heating rates.

Protonic conductivity and ferroelastic instability in triammonium hydrogen disulphate: a dielectric and neutron diffraction study
TL;DR: In this article, a phenomenological two-orderparameter model for the - ferroelastic phase transition was proposed, where properties which originate from the disorder of the oxygen and proton subsystem can be described by irreducible representations of the wave vector at the point and the L point of the Brillouin zone of the paraphase.
