Description

The fuel supply control system that is used for fuel cell system

Technical field

The utility model relates to fuel cell, relates in particular to a kind of fuel cell system fuel reaction control device, with auto-control mode, whether enters fuel system in order to monitoring and operation outside air.

Background technology

Existing fuel cell is to utilize hydrogen-containing fuel such as methyl alcohol, after redox reaction, forms current circuit, in order to the need of power supply to be provided.It utilizes the transducer according to high low water level in the control method of supply of fuel, judge whether to change the methanol concentration of whole anode reaction groove because the change of concentration adds high concentration methanol in good time.But its prior art only has the sensing of high low water level, lacks flexibility to adjust mechanism, and is used for the assembly of sensing, is with general built-in metal electrical sensor, can chemically contact action be arranged with the anode reactant groove unavoidably.Improve the disappearance of prior art in the utility model, it improves disappearance three, one, for more resilient concentration adjustment, the anode reactant groove is divided into 20 rank, each stratum represents 5% concentration water level respectively, and can see through control circuit, define high low water level voluntarily, to meet the demand of any load, they are two years old, the transducer of built-in contact improves, adopt non-contacting smooth cut-off, it is arranged at the both sides of anode reaction fuel bath, because the anode reaction cell body is a transparent unit, via control circuit monitor optical cut-off, judged whether that the light signal passes through, and then analyzed the position of present concentration water level that Photo Interrupter is a contactless sensing, can not be subjected to the influence of chemical solution in the anode reactant groove, its three, control circuit comprises a micro treatmenting controller, can be via setting, store defined high low water level relative position, and can handle light blocking signal, reach electromagnetic valve switch, but reach the control of program, and via the micro treatmenting controller analysis and with its quantification, quantized values can be found expression on the display screen, can allow user's Direct observation residual fuel amount.The present invention can be applicable to the fuel-cell fuel control of any load, is not confined to a certain fixed form, has elasticity.

The utility model content

The purpose of this utility model is to provide a kind of fuel supply control system and supply of fuel control method of fuel cell system, can make fuel cell when producing electric power, keep the fuel concentration in certain fuel cell main body, and analysis and control by micro treatmenting device, allow the system of whole fuel cell flexiblely control.

Wherein, the fuel supply control system of fuel cell system, include 20 stratum transducer, 20 transducers are promptly arranged, be set up in the outside, both sides of anode reaction groove respectively, and both sides are to be positioned on the same level with the transducer of stratum, the transducer that it is set at 20 stratum is to utilize contactless light cut-off, and its light cut-off sees through electronic loop, with the electric signal that senses, send back microprocessor controller, this is that unidirectional signal transmits, and its purpose is for informing micro treatmenting controller, in the anode reaction groove, the concentration water level of fuel why at present.Again, transducer wherein is made of the light cut-off, the light cut-off is a reflector and receiver, be placed in the both sides of anode reaction groove respectively, when fuel surpasses the level height of transducer, because of the light signal that transmits, because of the liquid level refraction, make the light signal can't be passed to corresponding optical receiver, so, transmit back micro treatmenting controller, after the treated analysis via electronic loop, the position of its place concentration water level of decidable, also, why all light blocking control device will can be learnt present concentration by analysis together owing to include 20 stratum, otherwise, if the light signal can be passed to corresponding optical receiver,, transmit back micro treatmenting controller via electronic loop, know that the fuel in the anode reaction groove has been lower than this horizontal plane, promptly indicated concentration has been lower than this concentration.Its sensing range is 20 stratum, so distinguish with the concentration water level, for per 5% being a sensing range, the 0th rank sensing is positioned at the bottom of anode reaction groove, and the 19th rank are the position that is positioned at 5% under the anode reaction groove top, this kind sensing mode is that contactless sensing can not be subjected to the influence of fuel in the anode reaction groove.

Moreover, microprocessor controller is to utilize to have the control mode of SMBUS interface, SMBUS is that SMBUS (System Management Bus) then is the interface that Intel and Duracell (goldentop battery) work out the used intelligent battery of mobile computer (Smart Battery) Shi Suofa wound jointly, be PC period the period of its development, advanced configuration and power-management interface (AdvancedConfiguration ﹠amp; Power Interface; ACPI) become basic administration message passing interface, control passing interface in the standard.Wherein, two main pin positions being arranged in SMBUS, be respectively SMBDATA and SMBCLK, is respectively the transmission of data and clock pulse, and other device can see through SMBUS chip communication therewith, obtains temperature and relevant information, or carries out order and control.And microprocessor controller is responsible for analyzing the light blocking signal of returning via the electronic loop transmission, and this signal is quantified as numerical value, it is transmitted on the display screen, allow fuel concentration water level in the anode reaction groove, can be known, the preparation of guarantee fuel can be provided in good time by the user.When the fuel that is mounted to the anode reaction groove when guarantee fuel enters the hole, open valve is subjected to the control of microprocessor controller, open or keep and close, and the unlatching of microprocessor controller control to be the concentration level detecting result who is set decide, and this concentration level can be set via supplier's elasticity of fuel cell, to keep best fuel cell operation status.

The beneficial effects of the utility model have three: one, the anode reactant groove is divided into 20 rank, each stratum represents 5% concentration water level respectively, and can see through control circuit, define high low water level voluntarily, to meet the demand of any load, can realize more resilient concentration adjustment, they are two years old, the transducer of built-in contact improves, adopt non-contacting smooth cut-off, it is arranged at the both sides of anode reaction fuel bath, because the anode reaction cell body is a transparent unit, via control circuit monitor optical cut-off, judged whether that the light signal passes through, and then analyzed the position of present concentration water level that Photo Interrupter is a contactless sensing, can not be subjected to the influence of chemical solution in the anode reactant groove, its three, control circuit comprises a micro treatmenting controller, can be via setting, store defined high low water level relative position, and can handle light blocking signal, reach electromagnetic valve switch, but reach the control of program, and via the micro treatmenting controller analysis and with its quantification, quantized values can be found expression on the display screen, can allow user's Direct observation residual fuel amount.In addition, the present invention can be applicable to the fuel-cell fuel control of any load, is not confined to a certain fixed form, has elasticity.
