664 Fuel Processing

Fuel processing depends on both the raw fuel and the fuel cell technology. The fuel cell technology determines what constituents are desirable and acceptable in the processed fuel. For example, fuel sent to a PAFC needs to be H2-rich and have less than 5% CO, while both the MCFC and SOFC fuel cells are capable of utilizing CO. PEMFCs require a pure hydrogen stream with less than 10 ppm CO. In addition, SOFCs and internal reforming MCFCs are also capable of utilizing methane (CH4) within the cell, whereas PAFCs are not. Contamination limits are also fuel cell technology specific and therefore help to determine the specific cleanup processes required.

Since the components and design of a fuel processing subsection depend on the raw fuel type, the following discussion is organized by the raw fuel being processed.
