Verfahren zur Konstanthaltung der Reaktionstemperatur eines Brennstoffzellenstapels

摘要

The fuel cell arrangement has an electrical output line (11) and an exhaust gas line (10) and associated auxiliary systems, such as reformers, a controllable fan (3) in an air line (5), a gas valve (4) in a gas line (6) and a controller (2) for maintaining a constant reaction temp. connected to the fan via a control line (15). The controller is connected via signal lines (12,14) to a vol. flow meter (9) in the gas line, a power meter in the electrical output line and a temp. sensor (7) in the exhaust line and is connected to a characteristic field memory (19) contg. experimentally determined possible operating states and associated air quantities.
