Abstract
Official abstract text for this publication.
A fuel cell stack 5 adapted for an electrochemical reaction of a fuel gas to generate an electric power is provided with a working point measuring section 51 for measuring a generation voltage and a generation current of the fuel cell stack 5, and connected to a controller 7 including an output characteristic map memory 72 for storing output characteristics of the fuel cell stack 5, and a potential output power estimator 71 for estimating a potential output power of the fuel cell stack 5 based on a combination of a current generation voltage V O and a current generation current I O measured by the working point measuring section 51 and pieces of information stored in the output characteristic map memory 72.
First claim
Opening claim text (preview).
What is claimed is: 1 . A fuel cell system comprising: a fuel cell configured for an electrochemical reaction of a fuel gas to generate an electric power; a working point measuring section configured to measure a working point defined by a combination of a generation voltage and a generation current of the fuel cell; an output characteristic map memory configured to store a set of maps adapted to map output characteristics of the fuel cell; and a potential output power estimator configured to estimate a potential output power of the fuel cell based on a combination of a current generation voltage and a current generation current measured by the working point measuring section and a set of pieces of information stored in the output characteristic map memory. 2 . The fuel cell system according to claim 1 , wherein the potential output power estimator is configured to estimate the potential output power of the fuel cell based on the current generation voltage, generation voltages associated with the current generation current on the output characteristics, and generation voltages associated with a given potential generation current of the fuel cell on the output characteristics. 3 . The fuel cell system according to claim 1 , wherein the potential output power estimator is configured to employ a linearity between characteristic curves as maps of the output characteristics on a voltage vs current coordinate plane, as a basis to estimate a potential generation voltage associated with a potential generation current stored in the output characteristic map memory from a current working point defined by the combination of the current generation voltage and the current generation current, to thereby estimate the potential output power of the fuel cell.
