- the present invention relates to an information processing apparatus including a fuel cell unit, a fuel cell unit, and a method of updating a program thereof.
- a lithium ion battery is used as a secondary battery which is one of power supply sources for an information processing device.
- One of the features of secondary batteries is that they can be used repeatedly, for example, by being charged using a commercial power supply, as compared with disposable primary batteries.
- the energy density of a fuel cell is theoretically said to be 10 times that of a lithium ion battery (for example, see Non-Patent Document 1).
- a fuel cell has the potential to be able to supply power for a longer period of time (for example, ten times) than a lithium ion battery, given the same volume or mass.
- the power supply times of the two are equal, it means that the fuel cell has the potential to be smaller and lighter than the lithium ion battery.
- a fuel cell does not require external charging if the fuel, for example, methanol or the like is sealed in a small container and united, and the small container is replaced and used. Therefore, for example, in places where there is no AC power supply, power is secured using lithium-ion batteries.
- the information processing device can be used for a longer time in the case where the electric power is secured by using the fuel cell as compared with the case in which the power supply is performed.
- Non-Patent Document 2 There are various types of fuel cell systems (see, for example, Non-Patent Document 2). However, considering that the fuel cell system is suitable for an information processing device, it must be small, light, and easy to handle. And a direct methanol fuel cell (DMFC) system. This type of fuel cell uses methanol as a fuel and injects methanol directly into the fuel electrode without converting it to hydrogen.
- DMFC direct methanol fuel cell
- the concentration of methanol injected into the fuel electrode is important, and if this concentration is high, power generation efficiency deteriorates and sufficient performance cannot be obtained.
- This is a phenomenon in which part of methanol as fuel passes through an electrolyte membrane (solid polymer electrolyte membrane) sandwiched between a fuel electrode (negative electrode) and an air electrode (positive electrode) (this is called a crossover phenomenon).
- the crossover phenomenon becomes more pronounced when the methanol concentration is high, and is reduced when low concentration methanol is injected into the anode.

- control program 95b stored in the storage unit 95a of the microcomputer 95
- the (old program) is updated to the update control program 95c (new program) sent from the power control unit 77 of the information processing device body 2 (S27).
- control program 95c for updating can be transmitted to the microcomputer 95 provided in the fuel cell unit by using a data bus (for example, an I2C bus) owned by the information processing device 1, a new data write is performed. No cable interface is required.
- a data bus for example, an I2C bus
- the update control program 95c can be easily input to the information processing apparatus main body 2 by using the LAN interface 85, the CD-ROM dryino 84, or the like of the information processing apparatus main body 2. .
- An update command can be transmitted by operating the information processing device main body 2, and the control program can be automatically updated only by transmitting the update command.
- the present invention is not limited to the above-described embodiment as it is, and may be embodied in a practical stage by modifying constituent elements without departing from the scope of the invention.
- Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. For example, some components, such as all components shown in the embodiment, may be deleted. Further, components of different embodiments may be appropriately combined.
- the control program of the fuel cell unit can be updated by a simple method.
