In order to create a device for testing a membrane electrode assembly, by means of which fabricated membrane electrode assemblies can be tested in a non-destructive manner, a first contact device is provided for bringing a first electrode side of the test object into electrical contact, a second contact device is provided for bringing a second electrode side of the test object into electrical contact, the first and second contact devices being electrically conductive at least in the contact area, and the first contact device and/or the second contact device having a plurality of electrically conductive contact segments spaced from one another, and a conductivity measuring device is provided for measuring the conductivity of the test object segmentwise in a location-- resolved manner.
L'objectif de l'invention est de cr~er un systme pour tester une unit~ membrane-~lectrodes au moyen duquel des unit~s membrane-~lectrodes nouvellement produites peuvent Útre test~es de fa×on non destructive. A cet effet, le systme selon l'invention comprend un premier dispositif de contact servant ~ ~tablir un contact ~lectrique avec une premire face d'~lectrode de l'objet ~ mesurer, ainsi qu'un second dispositif de contact servant ~ ~tablir un contact ~lectrique avec une seconde face d'~lectrode de l'objet ~ mesurer, le premier et le second dispositif de contact ~tant con×us de fa×on ~ Útre ~lectriquement conducteurs, au moins dans la zone de contact, et le premier dispositif de contact et/ou le second dispositif de contact pr~sentant une pluralit~ de segments de contact espac~s ~lectriquement conducteurs. Le systme selon l'invention comprend par ailleurs un dispositif de mesure de conductivit~ permettant de mesurer la conductivit~ de l'objet ~ mesurer segment par segment avec une r~solution locale.
