Abstract: A fuel cell stack structure in which unit cells are stacked includes first window frames and second window frame. The second window frames each have an area larger than an area of a first window frame and are periodically disposed at a predetermined interval in a direction in which the unit cells are stacked. Heat movement is promoted, a temperature deviation in the fuel cell stack structure is mitigated, and a temperature distribution is uniformized.

Abstract: The present application relates to a method for quantitative analysis of a polymer structure. Specifically, the method may be carried out through steps of measuring rheological properties and/or molecular weight distribution of the arbitrarily selected polymer, setting a random value for the selected polymer and then predicting the rheological property and/or the molecular weight distribution of the polymer from the random value, and comparing the measured value with the predicted value to determine the value of the structural parameter of the polymer.
