Hydrogen fuel cells require thermal uniformity. Is this an issue with the Direct Carbon Fuel Cell?
No. At a fixed power rating, the hydrogen fuel cell stack has roughly 4 times as much waste heat to dissipate, which requires heat exchangers to offset thermal non-uniformities. The lower waste heat in the Direct Carbon Fuel Cell is an advantage. 17. Question: DCFC Current Distribution. High temperature hydrogen fuel cells have had problems controlling non-uniform current distribution due to the progressive contamination of the hydrogen fuel with stream reaction products, which decreases the chemical potential of the fuel and leads to non-uniform heat production and incomplete fuel utilization. How will the Direct Carbon Fuel Cell control this critical operating parameter? Answer: The Direct Carbon Fuel Cell has a uniform current distribution and it is not subject to progressive contamination. In this sense, the Direct Carbon Fuel Cell is much less complex than the high temperature fuel cell. 18. Question: Hazard.
