An anode-supported tubular protonic ceramic fuel cell with BaCe0.7Zr0.1Y0.2O3-δ electrolyte is fabricated using dip-coating technique. Electrochemical performances of the are tested at temperatures from 600 to 200 °C, utilizing humidified H2 (3 vol% H2O) as and ambient air oxidant. With an effective area 2.3 cm2, yields a peak power density 465 mW cm−2 °C 118 450 °C. Even when temperature low there still output 3 mW. Stability under by operating constant voltage 0.7 V. The test lasts for 30...
Abstract Protonic ceramic fuel cells (PCFCs) using BaZr 0.8− x Ce Y 0.2 O 3− δ (BZCY) as electrolyte materials have attracted widespread attention because of their high performance at reduced temperature. However, there are few systematic studies on both the and stability BZCY materials. In this paper, we report our work electrochemical chemical ( = 0, 0.1, 0.3, 0.5, 0.7) series. The results show that electronic hole conductivity decreases with increasing 4+ content, especially addition, H 2...
Carbon is an important energy carrier. It abundant in the world, existing richly coal and biomass. Its released mainly through oxidation. A heat of ∼393 kJ may be obtained from complete oxidation 1 mol carbon. The most conventional method carbon combustion, which has problems pollutant emission low efficiency. However, electrochemical oxidation, chemical can converted into electricity with high efficiency pollution. Herein, we give a brief review our work on novel technology generating...
Transition metal oxides have been used as sintering aids for proton-conducting barium cerate-zirconates, which are promising electrolyte materials low-temperature solid oxide fuel cells (SOFCs) and high-performance electrochemical membrane reactors. However, the effects of additives on properties other than density electrolytes ignored. Here, we report our findings that transition also affect electrical properties, stability, even catalytic activity ABO3-type perovskites....
The solid oxide cell (SOC) based on a proton-conducting electrolyte is promising to play an important role in large-scale energy storage and hydrogen production. However, its development hindered by performance degradation caused the mismatch thermal expansion coefficients (TECs) between oxygen electrode. Although there work reducing TECs of electrode, it difficult find proper materials having low TEC while maintaining high performance. In this paper, we propose new path solve problem:...
Abstract The delicate design of efficient air electrodes is conducive to improving the reaction kinetics and operational durability protonic ceramic electrochemical cells (PCECs) at intermediate‐low temperatures. Here, a series high‐order Ruddlesden–Popper (RP) perovskite are developed via regulation Ni/Co ratio porosity for charge/gas transfer. As verified by structural analysis characterizations, electrode with composition Pr 4 Ni 1.8 Co 1.2 O 10‐δ (PNCO64) shows most matchable thermal...
Proton-conducting solid oxide cells are regarded as promising solid-state energy conversion devices to realize the high-efficiency between electrical and chemical energy. However, high cost, easily reducible ion characteristics, large thermal expansion coefficient related valence state of traditional high-catalytic cobalt-based oxygen electrode unavoidable problems. Cobalt-free barium ferrite-based oxides with triple-conducting properties considered most prospective candidates for highly...
