Improved mechanical strength, proton conductivity and power density in an 'all-protonic' ceramic fuel cell at intermediate temperature.

Protonic ceramic fuel cells (PCFCs) have become the most efficient, clean and cost-effective electrochemical energy conversion devices in recent years. While significant progress has been made in developing proton conducting electrolyte materials, mechanical strength and durability still need to be improved for efficient applications. We report that adding 5 mol% Zn to the Y-doped barium cerate-zirconate perovskite electrolyte material can significantly improve the sintering properties, mechanical strength, durability and performance. Using same proton conducting material in anodes, electrolytes and cathodes to make a strong structural backbone shows clear advantages in mechanical strength over other arrangements with different materials. Rietveld analysis of the X-ray and neutron diffraction data of BaCe0.7Zr0.1Y0.15Zn0.05O3-δ (BCZYZn05) revealed a pure orthorhombic structure belonging to the Pbnm space group. Structural and electrochemical analyses indicate highly dense and high proton conductivity at intermediate temperature (400-700 °C). The anode-supported single cell, NiO-BCZYZn05|BCZYZn05|BSCF-BCZYZn05, demonstrates a peak power density of 872 mW cm-2 at 700 °C which is one of the highest power density in an all-protonic solid oxide fuel cell. This observation represents an important step towards commercially viable SOFC technology.

Data on FTIR, TGA - DTG, DSC of invasive pennisetum purpureum grass.

The aim of this research is to characterize the invasive grass, Pennisetum purpureum, to evaluate the potentiality of the bioenergy production. Fourier transform infrared (FTIR) spectra are measured in order to understand the functional groups and their structure in the biomass. The thermogravimetric analysis (TGA) and the derivative thermogravimetric analysis (DTG) data are provided under Pyrolysis (N2) and combustion (O2) conditions to reveal the degradation pattern of the biomass. Differential scanning calorimetry (DSC) is the thermochemical process to measure the enthalpy changes pattern of the biomass. The original data presented in this work can be found in a research paper titled "Evaluation of the bioenergy potential of invasive Pennisetum purpureum through pyrolysis and thermogravimetric analysis", by Md Sumon Reza, Shafi Noor Islam, Shammya Afroze, Muhammad S. Abu Bakar, Rahayu S. Sukri, Saidur Rahman, and Abul K. Azad [1].

Neutron and X-ray powder diffraction data to determine the structural properties of novel layered perovskite PrSrMn2O5+δ.

The data presented in this article are related to the formation of a novel layered perovskite oxide material, PrSrMn2O5+δ, through a solid-state synthesis route. Here, we present the high-resolution neutron powder diffraction and the X-ray powder diffraction data at room temperature. The new perovskite material crystallizes in the orthorhombic symmetry. Interpretation of this data can be found in a research article titled "Insight of novel layered perovskite PrSrMn2O5+δ: A neutron powder diffraction study" (Shammya et al., 2019) [1].
