Mechanical properties were tested and compared at different temperatures and stress conditions.
Which convert the chemical fuel gas into electrical energy via electrochemical reaction. it has the double advantages of non-polluting and high power generation efficiency.The service-life of the fuel cell stack is an important factor which had a major influence on its commercialization.The anode creep and high temperature corrosion are the major factors affecting the service life of MCFC.
Cu and Ni have similar chemical properties, and its thermodynamic stability under fuel cell anode atmosphere is relatively stable through calculation.
Since MCFC is stacked by a plurality of cells, and wrapped by the outer seal parts, the anode materials are subject to the pressure load under the working conditions, it’s very important to study the compression performance of the anode materials. especially there’s no report on the study of creep properties of porous copper alloy about the Cu alloy.

The paper presents a study of the effect of technological parameters on the bending strength of pressed bamboo pulp plywood in order to enhance the mechanical properties of a new domestic product of construction in Vietnam. 1.
In the 2n DOE, 2 subtypes are full empirical factor and empirical partial factor [5]: Full planning is a simple experimental plan, when each element has 2 levels; the number of influential parameters is n so the number of experiment is a form of 2n.
The accuracy of the regression equation is worse than the full empirical factors DOE but it not much change if we only consider the combined effect of the two parameters.
The full empirical factors DOE for receiving best result because we only analyze the effects of the three most influential parameters.
