Abstract
A cell arrangement for an electrochemical energy converter, especially a fuel cell arrangement with cells (12) arranged in the form of a cell stack (10), is described. Each of the cells (12) comprises an anode (1), a cathode (2), and an ion-conducting layer (3) positioned between the anode and the cathode, and the cells are separated from on another and electrically contacted via bipolar plates (4). According to the invention, current collectors (4a, 4b) provided for contacting the anodes (1) or the cathodes (2) are formed by a porous structure, in which flow paths (16, 17) for conducting anode and/or cathode medium are contained.
