Is Steam an Oxidant or a Reductant for Nickel/Doped-Ceria Cermets?

Nickel/doped-ceria composites are promising electrocatalysts for solid-oxide fuel and electrolysis cells. Very often steam is present in the feedstock of the cells, frequently mixed with other gases, such as hydrogen or CO . An increase in the steam concentration in the feed mixture is considered accountable for the electrode oxidation and the deactivation of the device.

Fuel cells are a commercially viable alternative for the production of "clean" energy.

Fuel cells present a highly efficient and environmentally friendly alternative technology for decentralized energy production. The scope of the present study is to provide an overview of the technological and commercialization readiness level of fuel cells. Specifically, there is a brief description of their general advantages and weaknesses in correlation with various technological actions and political strategies, which are adopted towards their proper positioning in the global market.
