It is possible for a single component to achieve multifuel-processing.
Most hydrocarbon fuels warrant a fuel reformer or a cracker prior to feeding it to the SOFC stack. When designing and developing a multi-fuel system, it is of utmost importance to have single component or unit which is capable of processing and reforming different fuels.
The hypothesis here is that it is indeed possible to have a single component which can process and reform multi-fuels by:
- Selecting appropriate materials for the component itself;
- Selecting catalysts which can assist in reforming reactions of more than one fuel;
- Carefully optimizing the operating conditions in a manner that ensures high efficiency, durability, and lifetime of the stack. The schematic of such a multi-fuel processor is shown in Figure 1.
