摘要:
A damage calculation unit (2, 3) performs: acquiring a charge current value, a charge period, and a representative temperature of the electricity storage device while the electricity storage device is being charged, calculating a cycle damage number for representative temperature based on the obtained values, and integrating the cycle damage number for representative temperature; and acquiring a representative temperature of the electricity storage device in at least an operation state out of the operation state and a storage state, and an elapsed period at the representative temperature, calculating a calendar damage number based on acquired values of the representative temperature and the elapsed period, and integrating the calendar damage number.
摘要:
A fuel cell includes an electrolyte membrane, an anode on one surface of the electrolyte membrane and having an anode catalyst layer that is supplied with fuel and contains a platinum-ruthenium alloy catalyst, and a cathode on the other surface of the electrolyte membrane and having an cathode catalyst layer that is supplied with air and contains a platinum catalyst. The anode catalyst layer and the cathode catalyst layer include divided catalyst segments, and gaps between the divided catalyst segments that are adjacent to each other.
