Hydrocarbon reformer performance sensing system

摘要: In a fuel cell system, reformer supplies reformate to stack. A portion of the flow is diverted for analysis by hydrocarbon system. Residual hydrocarbons in may damage anodes Although incompletely-reformed include variety compounds, invention simply measures methane as an indicator overall performance level reformer. currently preferred embodiment includes catalytic combustion sensor. Combustion air and are delivered fixed ratio sensor via positive displacement pumps. The system can provide alarm means or optionally shut-off protect stack from elevated levels stream.
