1. An integrated hydrogen fueling station for fueling of vehicle tanks with hydrogen comprising an electrochemical compressor in which secondary hydrogen originating from leakage, boiling-off or venting of hydrogen-containing gas in one or more mechanical hydrogen compressors is collected and transferred to the electrochemical compressor and compressed by the electrochemical compressor, wherein the secondary hydrogen contains hydrogen and further gaseous components.
