信頼性の高い熱・電気併給発電を行なうことができる。In the fuel processing equipment, the reformed fuel for power generation, which is given in the form of heat and chemical energy by the catalyst layer from the heat source, is supplied to the heat exchanger, where it continues to enter the processing equipment (reforming). By returning the imparted thermal energy to the previous power generation fuel, a power generation fuel to which only chemical energy substantially close to room temperature has been imparted can be obtained.The room temperature fuel to which this energy has been imparted is used as a heat source. Even if the fuel processing equipment and power generation equipment are far apart, fuel can be transported with almost no heat loss.Also, since the energy imparted by the fuel processing equipment is close to room temperature, it can be easily stored. As a result, the fuel flow rate can be flexibly changed according to the load on the power generation equipment, allowing power generation with excellent load response and the fuel processing equipment to be operated under constant conditions, improving the reliability of the fuel processing equipment and reducing costs. In addition, since the temperature of the fuel supplied to the power generation equipment is close to room temperature, inexpensive fuel flow rate and pressure regulators can be used, reducing costs even in systems consisting of multiple power generation equipment. Performance is good;
Highly reliable combined heat and electricity generation can be performed.

FIG. 9 shows a case where the power generation device is a fuel cell 30, and a part of the heat exchanger partition wall 33 of the heat exchanger 5 is made of a porous wall. Oxidizing gas remains in the exhaust gas 10' of the oxidizing gas 10 that has exited the fuel cell 30, and part of it is used as power generation fuel to which chemical energy has been added through the porous portion 34 of the heat exchanger partition 33. The temperature of the fuel 9 can reach the operating temperature condition of the fuel cell by the reaction heat and the heat exchanged. In particular, when the fuel cell starts up from a cold state, the oxidizing gas 10 for the power generation device is hardly consumed and is discharged outside the fuel cell 30, so the oxidizing gas 10 at a low temperature inside the heat exchanger 5
The higher the concentration, the more the amount of reaction with the fuel in the heat exchanger increases, and the rise in fuel temperature increases accordingly, allowing the cell operating temperature to be reached in a short time. therefore,
The fuel temperature can be automatically raised to the operating temperature without applying heat from the outside, and once power generation starts, the oxidant gas concentration in the exhaust gas 10' discharged from the fuel cell 30 decreases, and accordingly. Since the amount of direct reaction with fuel within the heat exchanger is reduced, the rise in fuel gas temperature is also small, making it possible to always maintain a constant operating temperature.
