Abstract
A server apparatus includes a communication interface, a memory, and a controller. The memory stores correspondence information associating a travel history of a first vehicle configured to run on a fuel cell as a power source with a state of deterioration of the fuel cell. The controller receives, via the communication interface, information on a travel history from a second vehicle configured to run on a fuel cell as a power source, and outputs a notification about the fuel cell of the second vehicle based on the information on the travel history and the correspondence information.
Claims15
A server apparatus comprising:
- a communication interface;
- a memory storing correspondence information associating a travel history of a first vehicle configured to run on a fuel cell as a power source with a state of deterioration of the fuel cell determined based on a position of a deteriorated cell in the fuel cell;
- and
- a controller configured to
- receive, via the communication interface, information on a travel history from a second vehicle configured to run on a fuel cell as a power source, and
- transmit, via the communication interface to the second vehicle, a notification about the fuel cell of the second vehicle based on the information on the travel history of the second vehicle and the correspondence information,
- wherein the state of deterioration of the fuel cell of the first vehicle is determined to be:
- deterioration of a membrane when the position of the deteriorated cell in the fuel cell of the first vehicle is on an edge of a stack of cells of the fuel cell;
- deterioration of a catalyst when the position of the deteriorated cell in the fuel cell of the first vehicle is near a center of the stack of the cells of the fuel cell;
- existence of a contaminated or defective cell when the position of the deteriorated cell in the fuel cell of the first vehicle is a predetermined position from the edge of the stack of the cells of the fuel cell;
- and
- age related deterioration when each of the cells in the fuel cell of the first vehicle is uniformly deteriorated.

- deterioration of a catalyst when the position of the deteriorated cell in the fuel cell of the first vehicle is near a center of the stack of the cells of the fuel cell;
- existence of a contaminated or defective cell when the position of the deteriorated cell in the fuel cell of the first vehicle is a predetermined position from the edge of the stack of the cells of the fuel cell;
- and
- age related deterioration when each of the cells in the fuel of the first vehicle is uniformly deteriorated.
