BIPOLAR PLATE FOR STACK ASSEMBLY AND CASCADE TYPED STACK ASSEMBLY IN FUEL CELL SYSTEM

摘要

Provided is to implement the input amount of fuel supplied to a stack assembly 1, which is the same as the supply amount for generating a designed output value in operation, when the stack assembly 1 has a multiple stage cascade type using first, second, third, fourth, and fifth stack stages that are independently divided. Even if the input value is set to as 1 in order to acquire an output value of 1, the intermediate input value and the intermediate output value of each stage are changed more than 1 while the input value of 1 passes through the second, third, and fourth stack stages after passing through the first stack stage and the output value finally created through the fifth stack stage become 1, such that the cascade type multiple stage stack assembly 1 that increases the coefficient of utilization of fuel can be implemented.
