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&#xb0; C., well in excess of that for poly-fluorinated compounds presently used in electrochemical membranes and sensors.

Proton-conducting polyamide polymer membrane and method for production

The invention described the highly conducting amorphous polymer materials which are based on the pure block-type copolymers, which contain polyethylene oxide and other chemically complementary blocks and form the amorphous hydrogen-bonded intramolecular polycomplexes, and those, filled by ion conductive materials, low-molecular-weight organic plasticizer and nanometer-scale inorganic particles. The block-type copolymers are preferably the linear triblock copolymers with a central block of PEO and two side blocks of chemically complementary polyacrylamide (PAAm) or poly(acrylic acid) (PAAc). Due to existence of long side PAAm chains and their interaction with a central crystallizable block of PEO, TBC bulk structure is amorphous and fully homogeneous. It can be represented as a totality of hydrogen-bonded segments of both polymer components, uniformly distributed in PAAm matrix. Presented polymer materials can be used for solid polymer electrolyte for DSSC solar cells and lithium batteries.

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. Deviations of these parameters from the corresponding average values preliminary obtained on the training sample set of batteries is calculated. Probability density function binary signals are formed for deviations of parameters used. The batteries being diagnosed are rejected by means of using the obtained binary signals with their probability values and a logical rule set.
