Abstract:
1. An electrochemical hydrogen flow rate control system comprising: a hydrogen gas supply; an electrochemical cell including a first electrode for generating protons from the hydrogen gas supply, said first electrode on a first side of the electrochemical cell, a second electrode for converting the protons generated by said first electrode into hydrogen gas on a second side of the electrochemical cell, and a proton conductive solid electrolyte membrane fixed between the first and second electrodes; and a hydrogen flow rate control unit for generating a specific molar flow rate of hydrogen gas on the second side of the electrochemical cell, wherein a first partial pressure of the hydrogen gas supply on the first electrode is approximately equal to a second partial pressure of the hydrogen gas generated on the second side of the electrochemical cell, wherein the proton conductive solid electrolyte membrane includes a fullerene derivative composed of one or more fullerene molecules with carbon atoms having one or more proton dissociative groups introduced thereto.
