A method and a system for optimizing a lifetime of a fuel cell system based on adjustment and constraint of a thermoelectric ratio are provided. The method includes obtaining initial reference voltages of a plurality of single-machine fuel cell systems, and performing a durability test under a normal operating condition to obtain variation relationships of reference voltage over time; monitoring an operating voltage of each of the single-machine fuel cell systems in real-time under the normal operating condition to obtain a real-time monitored voltage and a real-time voltage deviation; calculating a performance expected attenuation profile of each of the single-machine fuel cell systems under the normal operating condition; obtaining current density distribution and actual available heat of each of the single-machine fuel cell systems, and calculating a health state boundary of each of the single-machine fuel cell systems in stable operation, so as to optimize operating modes of the systems.

The present disclosure relates to a device and a method for valuating a heat dissipation capability of a test platform of hydrogen fuel cell system. A plurality of PTC heaters are connected in series or in parallel in a primary or secondary dispersion water loop to simulate the fuel cell system with different heating powers. A rotation speed of water pump and whether a PTC is operated are controlled, thereby implementing steady and dynamic tests, and a test for integrative operating condition, thereby avoiding a real machine test from controlling a plurality of parameters. Compared with the real machine of a fuel cell, it can better test the heat dissipation capability of the fuel cell system. During the operation, the device does not need to be supplied reaction gases to ensure the safety of the test. The primary and secondary dispersion tests can be performed separately or in parallel.

The invention discloses a method for detection of genetically modified maize BT11. The principle of the method is that the DNA template of the sample is amplified at a temperature of 63&#xb0; C.&#x2dc;65&#xb0; C. for 45&#x2dc;60 min by using 4 specific primers and a DNA polymerase with strand displacement activity. The identification thereof is to make a judgment on whether BT11 component is contained in the sample by directly observing the turbidity in the reaction tube or the color change after the addition of SYBR Green with naked eyes or by agarose gel electrophoresis. The detection method of the invention has the advantages of high specificity, quickness, simplicity and convenience and the like, which provides a convenient method for detection of genetically modified maize BT11 with an extensive application prospect.
