Cabinet i.e. switch cabinet, for accommodating power supply systems, has power supply systems spaced from side wall of cabinet, and air guiding channels staying in connection with interior of fuel cell stacks of power supply systems

摘要

The cabinet (1) has a module comprising modular power supply systems (3, 4) that are integrated with fuel cell stacks i.e. polymer electrolyte membrane (PEM) fuel cell. The power supply systems spaced from a side wall (7) of the cabinet are mounted in the cabinet. Air guiding channels (33, 35) stay in connection with the interior of the fuel cell stacks of the power supply systems. Cooling air is transmitted to the fuel cell stacks as a part of reactant air guided in the air guiding channels, where the reactant air is preheatable by exhaust air from the fuel cell stacks.
