Gas distribution element, especially for fuel cell system, has integral measurement board with segments via which local current distribution can be measured, current tapping elements

摘要

The gas distribution element has gas chambers (26) and an integral measurement board (12) with a number of measurement segments (36) via which a local current distribution can be measured and a number of current tapping elements (34) for contacting an electrode and carrying currents to the measurement board in the perpendicular direction. AN Independent claim is also included for the following: a contact plate for positioning between an electrochemical cathode and anode and a fuel cell stack.
