Proton-exchange membrane fuel-cell power generating equipment includes a heat exchanger coupled to a process burner and, therethrough, to a fan. When water needs to be heated, such as during startup, the water is circulated through the heat exchanger and the process burner is operated (ignited) to heat the water. When the water needs to be cooled, such as when a hot water reserving tank is full, the water is circulated through the heat exchanger and the fan is operated, but the process burner is not operated, to cool the water. Water is circulated through part or all of a water system to prevent freezing while the system is stopped. Optionally, the process burner is operated to heat the circulated water. The heat exchanger and other heat exchangers in the system are arranged to efficiently recover heat from burners, a fuel-cell cooling system and exothermic processes.

Solid high polymer type fuel cell power generating device

There is provided a movable fuel cell apparatus comprising a movable housing, a power supply, and a fuel gas cylinder. The housing is divided into a front portion and a rear portion by a partition, and composed of a main housing body, a housing cover and a door. The main housing body has a front opening. The housing cover covers the upper portion of the front opening and the door is openably connected with the main housing body. The power supply included in the rear portion comprises a fuel cell for generating electric power by electrochemical reaction using fuel gas and air supplied. The fuel gas cylinder is placed removably in the front portion of the housing.
