How was the cost estimate for a large-scale Direct Carbon Fuel Cell determined?
The current design of the Direct Carbon Fuel Cell was costed by the providers of the components, and the cost is about $500 per square meter. This price is based on components which are now in mass production. 23. Question: Purification DCFC Fuel. Sulfur entrains in the anode of hydrogen fuel cells and this poisons the platinum and nickel catalysts at concentrations as low as 0.5 parts per million. How is such poisoning avoided in the Direct Carbon Fuel Cell? Answer: There are no catalysts to poison in the Direct Carbon Fuel Cell. The hydrogen fuel cell requires steam reforming, and then purification to prevent entrainment of sulfur into the anode. No steam reforming is required in the Direct Carbon Fuel Cell. In the IPFC, carbon, provided by the Hydrogen Plasma Black Reactor, is expected to be sulfur free, since the sulfur is volatilized as hydrogen sulfide and removed in the exhaust gas, serving as a minor marketable product. 24. Question: Molten Salt.
