Summary: This study investigates the potential and issues of laser ablation processes under DPLA and LS-PLA approaches through experiments and analysis. A novel technique of underwater nanosecond laser micro machining was adopted to address critical issues in microchannels processed by D-PLA approach. The phenomena behind the formation of channels in LS-PLA are different from those in D-PLA.

Summary: Protonic ceramic fuel cells show promise for energy conversion at intermediate temperatures. High order nickelates could be attractive cathode materials due to their high electrical conductivities. Composite cathodes in this study show improved performance, especially in wet O-2 conditions, with the correction of potential measurement biases.

Summary: The study investigated the impact of pulsed laser annealing on thin films made of boron and carbon atoms. The process led to the stratification of the films and the formation of a multi-phase structure involving g-BCx and B-doped GO/rGO. The preferential oxidation of boron and the incorporation of new chemical bonds were observed in the B-C-O system.

Summary: Systematic studies on BaZr0.8-xSnxSc0.2O3-delta revealed that the composition with x = 0.1 exhibits the highest values in terms of ionic and grain conductivities. Low-level substitution of Zr4+ with Sn4+ ions shows promise in designing new proton-conducting electrolytes for high-temperature applications.

Summary: In this study, we designed and prepared a high-entropy perovskite oxide (HEPO) BaCo0.2Zn0.2Ga0.2Zr0.2Y0.2O3-delta (BCX) as the cathode material for proton-conducting SOFCs (H-SOFCs), successfully addressing the interface degradation/separation issue between cobalt-based perovskite cathode and proton-conducting electrolyte. BCX cathode showed excellent oxygen reduction reaction performance and stability, with a low thermal expansion coefficient.

Summary: In this study, porous, fractal-like nanostructured carbon materials, known as carbon nanofoam, were fabricated using Pulsed Laser Deposition (PLD) technique. The role of key PLD parameters on nanofoam characteristics was investigated, and a comparison between nanosecond (ns-PLD) and femtosecond (fs-PLD) regimes was drawn. New insights about carbon nanofoam deposition and characterization were gained, opening new perspectives in the fabrication of nanostructured films with precisely controlled properties.

Summary: This research focuses on the development of K-doped BaCo0.4Fe0.4Zr0.2O3-delta (BCFZ442) series as cathodes for protonic ceramic fuel cells (PCFCs) and characterizes their crystal structure, conductivity, hydration capability, and electrochemical performance. The Ba0.9K0.1Co0.4Fe0.4Zr0.2O3-delta (K10) cathode exhibits the best electrochemical performance due to its high electron/oxygen ion/H+ conductivity and proton uptake capacity.

Summary: In this study, In-doped SrCe0.9In0.1O3-delta (SCI) and SrFe0.75Mo0.25O3-delta (SFM) were used as solid electrolyte and composite electrodes to construct symmetrical Protonic Ceramic Fuel Cells (PCFC). The SCI-SFM composite electrodes exhibited good mutual stability at high temperatures, enabling effective electrochemical reactions. The optimal 80:20 wt.% SFM-SCI electrode showed lower polarization resistance and higher power density compared to the 50:50 wt.% ratio, with similar performance in both PCFC and Protonic Ceramic Electrolyzer Cell (PCEC) modes.

Summary: The development of a bi-layered protonic ceramic fuel cell (PCFC) with a functional interlayer has been reported in this paper, showing improved electrochemical performance with higher power density and open-circuit voltage (OCV). The functional interlayer reduces cathode polarization resistance and suppresses current leakage in the PCFC, resulting in enhanced power density and OCV.
