coal directly into electricity?

Prof. George M. Whitesides from University of Harvard (
developed a prototype coal fuel cell using a solution of sub-bituminous coal (SBC) partially oxidized by Fe-III.
At 100 deg C, the maximum current density in the cell was 5 A/L and the power density was 0.6 W/L. The cell operated without loss of performance for 1000 hours.

It seems to be a great step forward in reducing the work-temperature for already existent MCFC (Molten Carbonate Fuel Cell) from 600C to 100C. (the main problem connected with high T is corrosion -

More technical details here ( a preprint article) :

I didn't manage to understand whether CO2 is also produced from the electrochemical process.
Someone can help?

See you!
