FUEL CELL SYSTEM

摘要

A leak in a fuel cell module (1) can allow hydrogen (H2) and/or oxygen (O2) to escape from the fuel cell module (1), hereby creating a high risk of fire or explosion. The invention addresses this problem by providing a fuel cell installation with a fuel cell module (1) that is enclosed in a gas-tight pressure container (3). Filling the pressure container (3) with a protective gas ensures that if the fuel cell module (1) does leak, no operating gas can escape from the module (1), protective gas entering the module (1) 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.
