摘要： There is provided a computer readable medium storing a subprogram causing a computer to execute a subprocess that includes a predetermined process performed in response to a call from a caller program and a return process to return the result of the predetermined process to the caller program. The subprocess includes: an address acquisition process that acquires an access destination address to be accessed by the subprogram before executing the return process, the access destination address being assigned to the memory area of the caller program; a determination process that determines whether or not the caller program is a legitimate caller program based on the acquired access destination address; and a termination process that, if it is determined that the caller program is not a legitimate caller program as a result of the determination, terminates execution of the subprocess before executing the return process.

摘要： In a fuel cell system and its controlling method, the fuel cell system includes a stack 21 including fuel cells 11 each having a polymer electrolyte membrane 13, and a controller 61. The controller 61 is responsive to detected outputs of a displacement sensor 27 and a temperature sensor 27 and controls such that, when the polymer electrolyte membrane 13 is discriminated to remain in an excessively dry state, a shut-off valve 37 is applied with a “close” control signal to interrupt the supply of fuel gas to the stack 21 and, concurrently, a shut-off valve 41 is applied with an “open” control signal to allow air to be supplied to the stack 21 while applying a pump control signal to a pump 57 so as to maximize its rotational speed for thereby increasing the flow rate of pure water 59 to be circulated to the humidifier 35 from a pure water tank 55. Simultaneously, a timer of the controller 61 is operated to begin counting an incremental time. As a result, air is excessively humidified by the humidifier 35 and is supplied to the stack 21 via the shut-off valve 41.

摘要： Fuel cell separators having on one side or both sides thereof channels for gas supply and discharge, which channels are formed from compositions composed mainly of thermosetting resin and graphite particles. The compositions are designed to have a flexural modulus of at most 20 GPa and a flexural strength of at least 50 MPa (both measured according to JIS K6911). Also disclosed is a solid polymer type fuel cell system in which part or all of its separators are fuel cell separators as defined above. Due to its high strength and low flexural modulus, the fuel cell separators of the invention do not break as a result of deformation at the time of fuel cell assembly. Moreover, the fuel cell separators of the invention absorb shocks and vibration imparted to the fuel cell system. Therefore, they is useful for automobile fuel cells which are normally subject to vibrations and shocks during operation.

摘要： A mold for producing a fuel cell separator with which a flash, even if it occurs, does not cause a thickness unevenness. The mold includes a plurality of molds 2, 4 and 10, and a fuel cell molding cavity 5 for separator being defined among the molds. At least one of the molds is provided with a flash reservoir cavity 11 which is communicated with the cavity 5. An amount of material in excess of the volume of the cavity 5 is charged, and melted by the application of pressure and heat. The melted material fills up the entire cavity 5, with the excess thereof entering the cavity 11. Since the molds 2 and 10 maintain a direct contact with each other, it is possible to obtain a separator molded with a high accuracy.
