摘要

A single H_2/Air fuel cell has potential of about 1 V at open circuit, which decreases to 0.6-0.7 V in operation as a function of current density. In order to increase the potential to some practical levels the cells are connected in a stack. A fuel cell stack consists of a multitude of single cells stacked up so that the cathode of one cell is electrically connected to the anode of the adjacent cell. In that way exactly the same current passes through each of the cells. Note that the electrical circuit is closed with both electron current passes through solid parts of the stack (including the external circuit) and ionic current passes through electrolyte (ionomer), with the electrochemical reactions at their interfaces (catalyst layers).
