Fabrication of an electrolyte-supported protonic ceramic fuel cell with nano-sized powders of Ni-composite anode

Electrochemistry and energy conversion features of protonic ceramic cells with mixed ionic-electronic electrolytes

“…In order to reduce the effects of undesirable electron transport of PCMs on the output properties of protonic ceramic electrochemical cells, the latter should be operated at low- and intermediate-temperature ranges. This strategy is constantly developing due to the design of new electrolyte materials, 121,138–141 novel thin-film technologies, 32,142,143 and innovative highly active electrode systems. 144–148…”

Nanotechnologies in ceramic electrochemical cells

“…Hwang et al fabricated Ni and Ba(Zr 0.85 Y 0.15 )O 3− δ (BZY) composite NPs via impregnating a precursor composed of Ni and BZY into the BZY scaffold at the fuel electrode followed by a calcination process at 900 °C. 247 The author considered that the low temperature sintering process for the fuel electrode generated the formation of a BZY and Ni nanocomposite with a size of 20–30 nm. A power output of 790 mW cm −2 at 700 °C was achieved on a 45 µm electrolyte-supported cell.…”

A review of progress in proton ceramic electrochemical cells: material and structural design, coupled with value-added chemical production

“…282 Similarly, a study involving Pd infiltration (2.0 wt% CeO 2 and 0.5 wt% Pd) on the Ni–BaZr 0.85 Y 0.15 O 3− δ (Ni-BZY8515) fuel electrode also demonstrated the contribution of nano-sized catalysts in reducing non-ohmic losses. 283 Moreover, the homogeneous Pd catalyst layer could be prepared by the atomic layer deposition (ALD) process. 284 The catalyst, which is present on the surface and penetrates into the porous electrode, improves the decomposition rate of NH 3 at intermediate temperatures, enhances current collection, and reduces R p .…”
