| Abstract(in English) | In this report, the effect of the temperature distribution in the stack on the amount of the work flow generation was experimentally examined. In order to actively change the temperature distribution in the stack, a method of heating the center of a stack was used in which a heat source was installed not only at one end of the stack but also at the center of the stack. As a result, when the central heating method was used, the amount of the work flow generation increased by about 1.6 times compared to the method in which only one end of the stack was heated. This is thought to be due to the fact that a temperature gradient is also formed at the room temperature end due to the center heating of the stack, and the amount of energy generation at the room temperature end increases. From the above discussion, it is suggested that the stack center heating method is effective in increasing the work flow generation. |
