When a conventional fuel cell module is shutdown the conditions within the fuel cell stack change. The conditions change because elements that support and regulate the operation of the fuel cell stack switch to their respective shutdown states. For example, the input and output valves are closed, which cuts off the supply inflows and exhaust outflows. Moreover, when an element such as a flow control device switches to a shutdown state internal conditions, such as for example, the pressure within the anode electrodes change. When the internal conditions of the fuel cell stack change the reactants (e.g. hydrogen and oxygen) remaining in the fuel cell stack and the feed lines (between the fuel cell stack and the closed valves) are substantially consumed in combustion reactions as opposed to being consumed in electrochemical reactions yielding a useful form of energy.

When a queue start instruction is input, a message queue control program starts a process of asynchronous communication and allocates a queue on a memory. Messages received from a message transmitting side application are stored into the queue. When a message receiving side application requires, the messages are transferred. When a queue shutdown instruction is input, the message queue control program saves the non-transferred messages stored in the queue to a saving file. When a queue restart instruction is input, the message queue control program acquires the messages saved to the saving file and restores them to the original queue.
