@GSKrasle:

The carbon gets sequestered in the carbonate electrolyte.  This point seems to be typically omitted or glossed over.  Another point (a disadvantage) is that these cells operate at high temperatures and would require relatively frequent maintenance.  On the positive side, they do a pretty good job of reducing CO2 emissions.

This is a bit confusing. I can't see where the carbon is supposed to end-up.

Looking at the fuel cell, working alone, it sounds like CH4 and O2 go in and CO2 and H20 come out somewhere, along with energy.

The power-plant, working alone, has C and O2 going-in one end, and CO2 and energy coming-out.

Put them together, CH4, C, O2 in, CO2, H2O out. 

Obviously, the amount of carbon in has to equal the carbon out. Also, it would be pointless if the carbon came out as CH4 or the element, as those are the fuels of the process, and would just be fed back in.

Is the point that the fuel cell more efficiently concentrates the CO2 than the standard process?
