<p>A power generation device including a hydrogen generator consisting of a reformer, transformer, purifier, gas flow passages connecting them together, and a produced gas exhaust port, and a polyelectrolyte fuel cell. The power generation device comprises the hydrogen generator (6), the polyelectrolyte fuel cell (1), a combustor (7) for heating at least the reformer, a flow rate controller (8) for controlling the supply amount of a combustion fuel, a communicating passage (10) between the combustor (7) and the flow rate controller (8), a merging unit (11) for merging residual fuel gases and an incomplete produced gas with a combustion fuel, and a connecting tube (12) for transmitting a pressure between the merging unit (11) and the flow rate controller (8) to the flow rate controller (8), wherein a combustion fuel supply amount is controlled by the above pressure, whereby a problem with a conventional power generation device is resolved that an incomplete produced gas conventionally exhausted to the outside, when the temperature of the hydrogen generator (6) is outside a preset temperature range such as at starting, is likely to ignite.</p> |
