Wind power causes fluctuations in power systems and introduces issues concerning system stability and power quality because of the lack of controllability of its discontinuous and intermittent resources. This paper presents a coordinated control strategy for solid oxide fuel cells (SOFCs) and superconducting magnetic energy storage (SMES) to match the intermittent wind power generation and comp...

Solid oxide fuel cells (SOFCs) technologies are considered the most efficient and environmentally-friendly option for both stationary distributed power generation due to their advantages of low pollution, noise strong building blocks. Despite potential, widespread adoption SOFC technology has not yet been achieved. The main reason is that high cost manufacturing maintenance insufficient operati...

Recently, many efforts and much attention has been paid to developing environmentally friendly energy. Solid oxide electrolyte cells (SOECs) process in reverse solid fuel (SOFCs) producing hydrogen gas as a green energy source. However, this application, high-performance catalysts are usually required overcome the sluggish oxygen evolution reactions (OER) during water decomposition. For reason,...

Formation of a heterostructure semiconductor materials is promising method to develop an electrolyte with high ionic conductivity at low operational temperature solid oxide fuel cells (LT-SOFCs).

Flowerlike CeO2 coated with Sr2Fe1.5Mo0.5Ox (Sr-Fe-Mo-oxide) nanoparticles exhibits enhanced conductivity at low temperatures (300-600 °C), e.g. 0.12 S cm(-1) at 600 °C, this is comparable to pure ceria (0.1 S cm(-1) at 800 °C). Advanced single layer fuel cell was constructed using the flowerlike CeO2/Sr-Fe-Mo-oxide layer attached to a Ni-foam layer coated with the conducting transition metal o...
