Working electrode holder and electrochemical cell

The present disclosure relates to a holder for a test object, more specifically to a holder for measuring electrochemical properties of the test object. One embodiment relates to a working electrode holder for measuring electrochemical properties of a front surface of a test object in a liquid, comprising: a housing comprising a bottom surface and a sidewall, the sidewall defining a first opening such that the test object can be placed inside the housing via the first opening and such that the front surface is facing the inner bottom surface; one or more electrically conductive pin(s) fixed to the bottom surface inside the housing such that the front surface of the test object is able to be placed on the pin(s), thereby providing an electrically contacted front surface, such that the electrically contacted front surface is able to operate as the working electrode; a second opening located in the bottom surface and configured for passage of said liquid, such that liquid is able to pass onto the electrically contacted front surface. The holder may be used in an electrochemical cell.
