A review of PEM fuel cell durability: Degradation mechanisms and mitigation strategies

Redox flow batteries, which have been developed over the last 40 years, are used to store energy on the medium to large scale, particularly in applications such as load levelling, power quality control and facilitating renewable energy deployment. Various electrode materials and cell chemistries have been proposed; some of the successful systems have been demonstrated on a large-scale in the range of 10 kW–10 MW. Enhanced performance is attributable to the improvements in electrodes, separator materials and an increasing awareness of cell design. This comprehensive review provides a summary of the overall development of redox flow battery technology, including proposed chemistries, cell components and recent applications. Remaining challenges and directions for further research are highlighted.

Photocathodic protection effect of TiO2 films for carbon steel in 3% NaCl solutions

The influence of polyethylene glycol (PEG), cetyltrimethylammonium bromide (CTAB), benzalacetone (BA), and thiourea (TU) on pulse electrodeposition of zinc from acidic sulfate baths was investigated by X-ray diffraction, scanning electron microscopy, and potentiodynamic polarization techniques. The results show that a mixture of PEG and CTAB can fully dissolve BA in the concentrated zinc sulfate solutions. This ternary additive can increase the overpotential of zinc electrodeposition markedly, and then gives rise to forming a bright nanocrystalline zinc coating on steel substrate, with an average grain size of 52 nm. The combination of these four compounds is more powerful for improving the cathodic polarization and inhibit hydrogen evolution during zinc electrodeposition in comparison with ternary additive systems. A bright and compact zinc coating with a grain size of 43 nm and the (110)(100)(201) preferred orientations are produced due to the coexistence of all four compounds. These compounds act in a synergetic way, especially between BA and TU, leading to the grain refinement of zinc deposits.
