File Description [top]

CEABA® - Chemical Engineering and Biotechnology Abstracts (CEABA) database contains references with abstracts, keywords, and bibliograpic details of international scientific and application-oriented literature on chemical engineering and biotechnology. It covers journals, conference proceedings, books, dissertations, and grey literature. Abstracts are in German and/or English. The CEABA database was published by DECHEMA e.v. up to May 2011. From June 2011 it has been produced by WTI-Frankfurt.

  /AB   ABSTRACT(ENGLISH):    Nafion(R)  (Dupont) membranes  are  perfluorosulfonic 
         proton conductors used  in  fuel cells, chlor-alkali  electrolysis  and 
         photoelectrochemical   systems.   A   method   for  the  recycling  and 
         regeneration   of  used  Nafion  membranes  based  on  dissolution  and 
         recasting  is  described.  Dissolution  was  conducted  using  dimethyl 
         sulfoxide  as a solvent under atmosphere pressure at 190 Cel , followed 
         by  recasting  at 170 Cel. The properties and performance of the recast 
         membrane   were   studied   using  X-ray  diffraction,  electrochemical 
         impedance  spectroscopy  and  cell  polarization measurements. The cell 
         performance with fresh and recycled membranes was similar.

  /AB   ABSTRACT(GERMAN):   Nafion  (R) der  Fa.  Dupont,  ein  Protonen leitender 
        Festelektrolyt  auf  Perfluorsulfonsaeurebasis  findet  aufgrund seiner 
        guten  thermischen,  chemischen und mechanischen Stabilitaet verbreitet 
        Anwendung   in   verschiedenen   elektrochemischen   Prozessen,  z.  B. 
        Brennstoffzellen,     Chloralkali-Elektrolyse    und    photochemischen 
        Prozessen.  Sowohl  aus  oekologischen  als  auch  aus wirtschaftlichen 
        Gruenden lag es nahe, mit zunehmender Verwendung nach einer brauchbaren 
        Recyclingmethode  fuer  diesen  nur  schwer  abbaubaren  Kunststoff  zu 
        suchen.   Fuer   den  Bereich  der  Brennstoffzellen  haben  die  Verf. 
        gebrauchtes  Nafion  (R)  115  bei  190  Cel unter Atmosphaerendruck in 
        Dimethylsulfoxid  geloest  und  bei  170  Cel  zu  einer neuen stabilen 
        Membran   mit   guter  kristalliner  Struktur  und  hoher  mechanischer 
        Stabilitaet   gegossen.   Die   Eigenschaften  dieser  Membran  (z.  B. 
        Wasseraufnahme,  Austauscherkapazitaet,  elektrischer  Widerstand) sind 
        aehnlich   wie   bei  einer  fabrikneuen  Membran  gleichen  Typs.  Das 
        Betriebsverhalten    der    mit   der   Recycling-Membran   bestueckten 
        Brennstoffzellen ist vergleichbar mit dem "frischer" Zellen.

1 Chemical substance names are segmented in all Basic Index fields; for example, DICHLOROBENZENE is retrieved when searched as a single term or as any of the segments: DI, CHLORO, BENZENE, CHLOROBENZENE. To search complete chemical words, use /FW; e.g., to search for records discussing benzene only, S BENZENE/FW.

2 Section Name includes the Cross Reference Section Name. and can also be searched with SH= and XR=.

3 Descriptors in English and German don't always overlap, so both languages should be searched.
