置されている。2. Description of the Related Art FIG. 4 is a longitudinal sectional view showing the basic structure of a conventional laminated fuel cell of this type. The cell 9 is formed by laminating a plurality of rectangular unit cells each having an electrolyte layer sandwiched between an oxidant electrode and a fuel electrode. The cooling plate 8 that is alternately stacked with the cells 9 to form a fuel cell stack serves to cool the cells 9 by removing heat generated due to power generation by flowing a coolant through an embedded cooling pipe. Plays. A manifold 7 is arranged on each side surface of the fuel cell stack, and is airtightly mounted on a carbon-based manifold mounting plate 6 arranged on both end surfaces of the fuel cell stack in the stacking direction. A current collector plate 4 is incorporated on the outside of the manifold mounting plate 6 via a graphite 5. Further, a tightening plate 1 for tightening and holding these laminated bodies, and an insulating plate 3 for maintaining electric insulation. And the heat insulating plates 2A and 2B for suppressing the temperature rise are arranged therebetween.

なる。In this configuration, when the manifold 7 is used to flow the oxidant gas from one side surface of one set of the fuel cell stack to the other side, and to flow the fuel gas from one side surface of the other set to the other side, An electrochemical reaction occurs in each of the cells 9 and a direct current power is generated between the pair of current collector plates 4, so that the lead wires 11 connected to the current collector plates 4 extract the cells to the outside.

よってセル９を加熱し、所定温度に保持する。Since the electrochemical reaction is an exothermic reaction, cooling is carried out by passing a refrigerant through the cooling pipe embedded in the cooling plate 8 as described above, and the fuel cell stack is maintained at a predetermined temperature for operation. To be done. When the operation is stopped, the heat generation is stopped and the temperature of the fuel cell stack is lowered. However, when the temperature is too low, the electrolyte layer of the cell 9 may become abnormal. Also, a method of keeping the temperature above a predetermined temperature is adopted. The heaters 10 attached to the tightening plates 1 at both ends in the stacking direction in FIG. 4 are used for this purpose, and are turned on when the operation is stopped, and the cells 9 are heated by conduction heat to maintain the cells at a predetermined temperature.

る。As described above, in the conventional laminated fuel cell, the cell temperature is kept above the predetermined temperature even when the operation is stopped by heating with the heater 10 attached to the tightening plate 1. The method of doing is adopted. However, in this method, the heaters 10 for heating are arranged on the fastening plates 1 on both end surfaces of the laminated fuel cell, and the heat insulating plate 2A is provided between the heater 10 and the cells 9 of the fuel cell laminated body whose temperature is to be controlled. Since the insulating plate 3, the heat insulating plate 2B, the current collecting plate 4, and the manifold mounting plate 6 are interposed, there is a drawback that the performance is poor. That is, among the above, the heat insulating plate 2A, the insulating plate 3 and the heat insulating plate 2B, in particular, have low heat transfer performance, so that there is a control delay between the temperature of the heater 10 and the temperature of the cell 9 so that proper control cannot be performed. There are points,
Further, since the heater 10 is arranged on the outermost side, the heating efficiency is poor and a large amount of heating power is required.

A manifold mounting plate, a current collecting plate, an insulating plate, and a tightening plate, which are sequentially stacked on the fuel cell stack, and a manifold which is arranged on the side surface of the fuel cell stack and airtightly mounted on the manifold mounting plate. In a laminated fuel cell in which agent gas and fuel gas are made to flow and DC power is taken out from a current collector plate, for example, a heater is embedded in a manifold mounting plate to form a heat retaining means, and a space is provided between the fuel cell stack and the current collector plate. In addition, the battery heat insulating means is provided.

熱することができ所要消費電力が少量となる。As described above, if the battery heat retaining means is provided between the fuel cell stack of the laminated fuel cell and the current collector, the fuel cell stack is heated by using this battery heat retaining means when the operation is stopped. In this case, since the cell heat retaining means and the fuel cell stack are close to each other and there is no insulating plate or heat insulator having poor heat transfer performance therebetween, good heat transfer performance can be obtained, so that the fluctuation range with excellent responsiveness can be obtained. A small temperature control is possible.
Further, since the battery heat retaining means is arranged inside the laminated portion unlike the conventional case, it can be effectively heated without being directly radiated to the outside, and the required power consumption is small.
