FUEL CELL INSTALLATION

摘要

A leak in a fuel cell module can allow hydrogen and/or oxygen to escape from the fuel cell module, thereby creating a high risk of fire or explosion. This problem is addressed by providing a fuel cell installation with a fuel cell module that is enclosed in a gas-tight pressure container. Filling the pressure container with a protective gas ensures that if the fuel cell module does leak, no operating gas can escape from the module, with protective gas entering the module instead. A leak therefore no longer poses a risk. The leak can also be identified and located by a voltage drop in the cells affected by the leak.
