A fuel cell system includes a fuel cell stack having a plurality of fuel cells that each contain a plurality of fuel electrodes and air electrodes. The system includes a fuel receiving unit connected to the fuel cell stack, which receives a hydrocarbon fuel from a fuel supply. The system includes a fuel exhaust processing unit fluidly coupled to the fuel cell stack by a slip stream, where the fuel exhaust processing unit processes fuel exhaust from the fuel cell stack, and the slip stream is fluidly connected to an exhaust stream flowing from the fuel cell stack. The fuel processing unit removes a first portion of carbon dioxide (CO) from fuel exhaust within the slip stream, outputs the first portion of COin a first stream, and outputs a second portion of COremaining from the fuel exhaust in the slip stream into a second stream, which includes hydrogen.

An apparatus for depressurizing a pair of accumulators to provide high pressure gas includes a tank in fluid communication with each one of the pair of accumulators for receiving vapor from the pair of accumulators for storage and dispensing the vapor to a remote location other than the pair of accumulators and external atmosphere, a first fluid connection including a first valve assembly interconnecting the tank and a first accumulator of the pair of accumulators, a second fluid connection including a second valve assembly interconnecting the tank and a second accumulator of the pair of accumulators, wherein the first fluid connection with the first valve assembly and the second fluid connection with the second valve assembly are each constructed and arranged to deliver the vapor from a corresponding one of the first accumulator and the second accumulator to the tank during alternating intervals. A related method and system are also provided.
