Patent number: 8557446Abstract: The present invention involves the synthesis, preparation and use of a new family of proton conducting polymer membranes. These proton-conducting polymer membranes are produced from the products of joint condensation of polyamides with sulfonated aromatic derivatives of aldehydes in the presence of solvent and acid catalyst. The resulting products have low equivalent weight, high ionic conductivity at room temperature, excellent proton function value, and insignificant change of geometrical size due to swelling in water and acid solutions. The products exhibit high mechanical strength and thermal stability to more than 150° C., well in excess of that for poly-fluorinated compounds presently used in electrochemical membranes and sensors.Type: GrantFiled: August 11, 2007Date of Patent: October 15, 2013Assignee: Enerize CorporationInventors: Oleg Chervakov, Elena Shembel, Yu Kobelchuk, Konstanlyn Gerasymenko

Patent number: 7783438Abstract: The present invention is an integrated method and apparatus for determining the quality of electrochemical energy storage devices, especially batteries. The invention is based on an integrated usage of electromagnetic and ultrasonic energy to probe of the interior volume of the battery. The first probe is carried out when the battery is at an initial charged state. After the first probe stage, a discharge of the battery being diagnosed is carried out until the test battery is at a small fixed test charge value. Signals from the eddy current probes allow determination of the continuity of the discharge current during the discharge process. After the discharge of the battery, the above described test sequence is repeated. The resultant eddy current signal generated at the initial state of the battery and the gradients of the eddy current signal and of the ultrasonic signal versus the battery capacity is determined.Type: GrantFiled: October 30, 2007Date of Patent: August 24, 2010Assignee: Enerize CorporationInventors: Volodymyr Redko, Volodymyr Khandetskyy, Elena Shembel
