Electrochemical hydrogen flow rate control system
First Claim
1. An electrochemical hydrogen flow rate control system comprising:
- an electrochemical cell including a first electrode for generating protons 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 amount of hydrogen gas 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.

Abstract
An electrochemical hydrogen flow rate control system is provided. The system has an electrochemical cell and a hydrogen flow rate control unit. The electrochemical cell includes a first electrode for generating protons (H+), a second electrode for converting the protons generated by said first electrode into hydrogen gas, and a proton conductive solid electrolyte membrane held between said first and second electrodes. The hydrogen flow rate control unit is adapted to generate a specific amount of hydrogen gas on the second electrode side. The proton conductive solid electrolyte membrane is made from a fullerene derivative obtained by introducing proton dissociative groups in carbon atoms of fullerene molecules. Such a control system is operable even in a non-humidified atmosphere and at room temperature and is configurable as lightweight and compact in system design.
