Abstract

A hydrogen desorption method includes a step of bringing a liquid containing an alicyclic saturated hydrocarbon having a tertiary carbon atom bearing a saturated hydrocarbon side chain, a quinone, and an electrolyte into contact with a anode and a step of desorbing hydrogen from the alicyclic saturated hydrocarbon having a tertiary carbon atom bearing a saturated hydrocarbon side chain.

First claim

What is claimed is:

1 . A hydrogen desorption method comprising:
bringing a liquid containing an alicyclic saturated hydrocarbon having a tertiary carbon atom bearing a saturated hydrocarbon side chain, a quinone, and an electrolyte into contact with a anode; and desorbing hydrogen from the alicyclic saturated hydrocarbon.

2 . The hydrogen desorption method according to claim 1 , wherein
the liquid further contains a polar solvent.

3 . The hydrogen desorption method according to claim 1 , wherein
the alicyclic saturated hydrocarbon is at least one of a monocyclic saturated hydrocarbon having a tertiary carbon atom bearing a saturated hydrocarbon and a polycyclic saturated hydrocarbon.

4 . The hydrogen desorption method according to claim 1 , wherein
the monocyclic saturated hydrocarbon having a tertiary carbon atom bearing a saturated hydrocarbon side chain contains at least one selected from the group consisting of methylcyclohexane and di methylcyclohexane.

5 . The hydrogen desorption method according to claim 1 , wherein
the quinone contains 2,3-dichloro-5,6-dicyano-p-benzoquinone.

6 . The hydrogen desorption method according to claim 1 , wherein
the quinone contains chloranil.

7 . The hydrogen desorption method according to claim 1 , wherein the hydrogen is desorbed from the alicyclic saturated hydrocarbon by applying a voltage between the anode and an cathode.

8 . The hydrogen desorption method according to claim 7 , wherein
the hydrogen is desorbed from the alicyclic saturated hydrocarbon by applying a direct voltage of 0.07 V or more to the anode with a single cell.

9 . The hydrogen desorption method according to claim 1 , wherein
the hydrogen is desorbed from the alicyclic saturated hydrocarbon by applying a direct voltage of 1.5V or less between the anode and the cathode with a single cell.

10 . The hydrogen desorption method according to claim 1 , further comprising:
conducting hydrogen desorbed on the anode to the cathode via a polymer electrolyte film.

11 . The hydrogen desorption method according to claim 10 , further comprising:
supplying a cathode fluid to the cathode; and humidifying the cathode fluid.

12 . A dehydrogenation apparatus comprising:
a liquid containing a quinone, an electrolyte, and an alicyclic saturated hydrocarbon having a tertiary carbon atom bearing a saturated hydrocarbon side chain; a storage chamber containing the liquid; a anode being in contact with the liquid in the storage chamber; and an cathode.

13 . The dehydrogenation apparatus according to claim 12 , wherein
the liquid further contains a polar solvent.

14 . The dehydrogenation apparatus according to claim 12 , wherein
the alicyclic saturated hydrocarbon is at least one of a monocyclic saturated hydrocarbon having a tertiary carbon atom bearing a saturated hydrocarbon and a polycyclic saturated hydrocarbon.

15 . The dehydrogenation apparatus according to claim 14 , wherein
the monocyclic saturated hydrocarbon having a tertiary carbon atom bearing a saturated hydrocarbon side chain contains at least one selected from the group consisting of methylcyclohexane and di methylcyclohexane.

16 . The dehydrogenation apparatus according to claim 12 , wherein
the quinone contains 2,3-dichloro-5,6-dicyano-p-benzoquinone.

17 . The dehydrogenation apparatus according to claim 12 , wherein
the quinone contains chloranil.

18 . The dehydrogenation apparatus according to claim 12 , further comprising:
a voltage application device applying a voltage between the anode and the cathode.

19 . The dehydrogenation apparatus according to claim 12 , further comprising:
a proton conductor between the anode and the cathode, the proton conductor being a solid polymer electrolyte film.

20 . The dehydrogenation apparatus according to claim 19 , further comprising:
a humidifier humidifying the cathode fluid to be supplied to the cathode.
