Abstract:
1. A load device for a cell stack, comprising: a balance plate, abutted exactly against the top of the cell stack; a first column, disposed on top of the balance plate; a second column, mounted on top of the first column; a load cell, disposed on top of the first column an elastic member, disposed on top of the load cell; an actuator, placed on top of the elastic member to be used for providing a load to the load cell, the elastic member and the first column in a manner that the first column is driven to press on the balance plate for enabling the same to exert a pressure on the cell stack; and wherein the balance plate and the first column are made of a material capable of resisting a high temperature that is at least 820° C.; and wherein the second column mounted on top of the first column in a coaxial manner and the second column fixes and positions the actuator, the elastic member, and the load cell by passing through centers of the actuator, the elastic member, and the load cell, and the second column is made of a material capable of withstand the heat transmitted from the first column.
