Abstract:
The world is using up non-renewable energy sources quickly. Fossil fuel-based energy
supplies may run out in a century and two decades. Fossil fuels have many harmful effect
on human health and environment. Although fuel cell have received a lot of interest
because there great efficiency, simplicity, low impact on the environment, cost effective
and fuel adaptability. All fuel cell types, solid oxide fuel cells (SOFCs) is gaining more
popularity. Ba-SDC, Sr-SDC, Ca-SDC & Ti-SDC was used as an electrolyte improve
properties of solid oxide fuel cell. Due to this purpose electrolyte material was synthesized
by co-precipitation method. Prepared material analyzed by various technique such as
Raman, UV-Visible, Fourier transform infrared spectroscopy, Conductivity measurement
& Open circuit voltage (OCV). Raman sample expose strong peak between 600cm-1 to
1200 cm-1
, which may be predict the vibration mode and change in structure. It describes
the kind of shifting that occur in prepared material. The presence of blue shift in material
may be shows heavy atoms in material by which its bound length got shorter and the red
shift predict bound length increase by increase by wavelength also it shows the active
modes (F1g, A1g and Eg). By UV-visible, synthesized sample's band gap and absorbance are
detected. FTIR provides information on the presence of functional groups in materials as
well as the organic or inorganic behavior of manufactured materials. With the aid of
temperature dependent EIS, the conductivity of materials may be computed. Ti-SDC shows
maximum conductivity at 700°C and having value 0.090 S/cm. Using hydrogen as fuel
improves the conductivity of materials by utilizing fuel cell performance at temperatures
ranging from 500°C to 700°C
