  • Infrared sensing of concentration of methanol's aqueous solution
    Patent number: 6815682
    Abstract: Systems and methods for infrared sensing a compound's concentration in aqueous solution are provided. In various non-limiting embodiments, the invention provides infrared sensing of methanol's concentration in aqueous solution in connection with a fuel circulation process for a direct methanol fuel cell. In some embodiments, flow-through infrared sensing technique are provided. In other embodiments, window type infrared sensing techniques are provided. As a result of the infrared sensing, an accurate real-time measurement of the concentration of a compound of interest in aqueous solution is affordably obtained.
    Type: Grant
    Filed: December 28, 2001
    Date of Patent: November 9, 2004
    Assignees: E. I. du Pont de Nemours and Company, ABB Research Ltd.
    Inventors: Arnold Rabinovich, Evangelos Diatzikis, Jeffrey Mullen, Daryl Tulimieri
  • Ultrasound sensing of concentration of methanol's aqueous solution
    Patent number: 6748793
    Abstract: Systems and methods for ultrasound sensing a compound's concentration in aqueous solution are provided. As a result of the ultrasound sensing, an accurate real time measurement of the concentration of the compound of interest in aqueous solution is obtained. In various non-limiting embodiments, the invention provides ultrasound sensing of methanol's concentration in aqueous solution in connection with a fuel circulation process for a direct methanol fuel cell. Since the speed of sound in a water-methanol system increases significantly with methanol content, techniques for measuring characteristic sound velocities are used to give sufficient resolution for a fuel circulation process.
