Abstract
This paper is dedicated to analytical expression of the maximum electricity-cost ratio (M-ECR) point of the proton ex change membrane (PEM) fuel cell power generation as the function of cell constants and cost constants. That is to for mulize the maximum cost performance (MCP) magnitude and the optimal final operating (OFO) location in the work ing zone based on the five-constant ideal cell model and the two-constant cost model. The issues are well resolved by introducing the concepts of economic voltage and cost factor and describing the movement of the M-ECR point with cost factor. According to mathematical derivations, the movement can be described in the form of MCP and OFO curves. The derivations lead to a complete set of discriminants and criteria of the M-ECR point of PEM fuel cells that theoretically cover all of cell specialties and all of cost specialties. The discriminants and criteria may act as a general tool for the operation optimization of a diversity of PEM fuel cells and the economic viability estimation of the power generation .
