  • Proton conductor and fuel cell
    Patent number: 11824241
    Abstract: A proton conductor is in contact with a catalyst containing platinum. The proton conductor includes a cationic organic molecule, a metal ion, and an oxoacid anion. A protic ionic liquid containing the cationic organic molecule and the oxoacid anion is coordinated to the metal ion to form a coordination polymer.

  • QUANTUM COMPUTER AND METHOD FOR CONTROLLING SAME, QUANTUM ENTANGLEMENT DETECTING DEVICE AND QUANTUM ENTANGLEMENT DETECTING METHOD, AND MOLECULE IDENTIFYING DEVICE AND MOLECULE IDENTIFYING METHOD
    Publication number: 20230014662
    Abstract: Provided is a quantum computer which makes it possible to easily carry out quantum calculation. A quantum computer (10) includes electrodes (20) and (21), a molecule (22) that is entirely or partially provided between the electrodes (20) and (21), and a current sensor 13 that detects a tunneling current which flows between the electrodes (20) and (21) via the molecule (22). The molecule (22) works as a quantum circuit for carrying out quantum calculation.

  • PROTON CONDUCTOR AND FUEL CELL
    Publication number: 20200220192
    Abstract: A proton conductor includes an anionic molecule and a cationic organic molecule. The anionic molecule is an anionic metal complex molecule. For example, the anionic metal complex molecule includes at least one chemical bond between a metal ion and an oxoacid ion. For example, the proton conductor can be used as an electrolyte membrane included in a fuel cell.
