Abstract
The invention relates to a fuel cell system with a hydrogen purification subsystem. The hydrogen purification subsystem can concentrate hydrogen from the fuel exhaust for recirculation or storage. The hydrogen purification subsystem can also concentrate hydrogen from a fuel supply for input into a fuel cell or for storage. The hydrogen purification subsystem can also concentrate hydrogen for quantitative comparison with a second stream containing hydrogen. The hydrogen purification subsystem can also charge a hydrogen storage device for system use such as meeting transient fuel cell load increases.
