Kind Code:
A3
Abstract:
Disclosed is a cooling arrangement for a high temperature fuel cell system for reducing the amount of purge gas in a system shutdown situation. The cooling arrangement comprises: a coolant source (120) capable of providing coolant to be used in a cooling process of the high temperature fuel cell system during the system shutdown situation, a cooling structure (122) in connection to the coolant source (120) and arranged in a thermal effect area of the fuel cell stacks (103) for receiving heat from the fuel cell stacks and transferring received heat to the coolant, means (124) for feeding said coolant into the cooling structure (122) from the coolant source (120), means (126) for exhausting used coolant from the cooling structure, and means (136) for utilizing a triggering force to trigger a coolant flow in the cooling structure, when the system shutdown situation has started.
