摘要： PROBLEM TO BE SOLVED: To provide an algorithm for a judgement of a polarization curve of a fuel cell stack.
SOLUTION: When the fuel cell stack is in operation and a predetermined data adequacy standard is satisfied, the algorithm enters into a data collection mode and stack data such as a current density, an average cell voltage and a minimum cell voltage are collected. When the stack is shut down, the algorithm solves an exercise of at least a square by using a cell voltage model and estimates a predetermined parameter to define a polarization curve. If the estimated parameter satisfies the predetermined completion standard, the estimated parameter is stored and is used by a system controlling device for calculating the stack polarization curve.

摘要： PROBLEM TO BE SOLVED: To provide a fuel cell system that employs an algorithm for limiting a current output from a fuel cell stack using a feedback during high stack temperature operation.
SOLUTION: The system includes a PID controller that receives an error signal which is a difference between a cooling fluid output temperature from the stack and a predetermined temperature value. The algorithm detects whether the cooling fluid output temperature is higher than the predetermined temperature value, and, if so, a proportional gain component and an integral gain component are calculated to set up a proportional gain and an integral gain of the PID controller. Based on the proportional gain component, the integrated gain component and the error signal, the algorithm generates an allowable total current and sets up a maximum current drawn from the stack. A rise or a fall from an actual current allowable from the stack is limited so that a smooth transition can be provided.

摘要： PROBLEM TO BE SOLVED: To provide a system and method for preventing the performance degradation of cells in a fuel cell stack.
SOLUTION: The method includes a step of periodically supplying a pulse 10 of a cathode input airflow at low stack current densities, and a step of comparing the current density output of each cell in response to the pulse 10. Those cells that do not have significant water accumulation exhibit one voltage feature 12 and those cells that do have a significant water accumulation exhibit another voltage feature. If one or more of the cells exhibit the voltage feature for water accumulation, then the cathode inlet airflow pulses are supplied more often to prevent the cells from failing.

摘要： PROBLEM TO BE SOLVED: To provide a method of deciding whether the possibility of freezing conditions exists when a normal system shutdown is proceeded, and performing a purge of reaction gas flow channel when the possibility of the freezing conditions exists. SOLUTION: The fuel cell system uses a method for deciding the possibility of existence of freezing conditions after the system is shut down based on predetermined inputs such as an ambient temperature, a geographical position, a date, and a weather information. When the system decides that there is a possibility of freezing conditions and freezing might occur, the system starts a purge shutdown of the fuel cell system, then water is purged from the reaction gas flow channel. When it decides that the system would not be frozen, it starts a normal shutdown treatment without proceeding the flow channel purging. This system periodically decides whether the terms of conditions are changed, then, when freezing conditions occur, the purge of the reaction gas flow channel is started. COPYRIGHT: (C)2008,JPO&INPIT
