Sažetak
In one embodiment an electrochemical cell system comprises: a fuel cell stack comprising a fuel cell having a fuel cell hydrogen inlet and a fuel cell hydrogen outlet, and a first electrochemical hydrogen compressor in fluid communication with the fuel cell hydrogen outlet, wherein the first electrochemical hydrogen compressor comprises electrodes in electrical communication with an electricity source, and a compressed hydrogen outlet in fluid communication with the fuel cell hydrogen inlet. In one embodiment the method of operating the electrochemical cell system comprises: introducing hydrogen feed to a fuel cell at a feed rate of greater than stoichiometry, directing excess hydrgoen from the fuel cell to a first electrochemical hydrogen compressor, electrochemically compressing the excess hydrogen and recirculating the compressed hydrogen gas to the fuel cell.
