Abstract
The common definition of a fuel cell electrical efficiency is not sufficient to achieve complete calculation control on a fuel cell, but this is possible by introducing the two efficiency concepts defined in the report. The `model` presented in this study makes it possible to show how the process`s total electrical efficiency varies with time of operation . The study shows that the stack voltage and the stack voltage decay rate are influential factors on a fuel cell cycle working in the concept. The fuel cell efficiency decreases until it has reached a point where heat produced by the fuel cell is not sufficient to keep its temperature high enough. This critical point is important and should be the basis for all life cycle calculations of the concept. The study shows, as well, that a high fuel cell pressure has no effect on the process`s total electrical efficiency. (au).
