Reversible cell efficiency is the ratio of fuel cell to electrolysis voltage at the same cell current and hydrogen/steam feed. It is a measure of the maximum possible energy storage efficiency for a reversible system using the cell (system efficiencies will be lower than cell efficiencies). The highest reversible cell efficiency observed was 90.8% (at 925 °C and 50 mA/cm ). [Pg.150]

For improving the energy storage efficiency, ECP/CNM nanocomposites are widely used in electrochemical energy storage devices. These include lithium-ion batteries and supercapacitors. Polyaniline/CNM nanocomposites and polypyrrole/CNM nanocomposites are the major composite nanostructures used for this piupose due to their superior electrochemical properties, low cost and easy processing methods.
