Abstract
Disclosed are methods and systems for generating hydrogen gas at pressures high enough to fill a hydrogen storage cylinder for stationary and transportation applications. The hydrogen output of an electrochemical hydrogen gas generating device, a hydrogen-producing reactor, or a diluted hydrogen stream is integrated with an electrochemical hydrogen compressor operating in a high-differential-pressure mode. The compressor brings the hydrogen produced by the hydrogen generating device to the high pressure required to fill the storage cylinder.
