Organic liquid heating and heat preservation device for organic liquid fuel cell automobile

Abstract

The invention provides an organic liquid heating and heat preservation device for an organic liquid fuel cell automobile. The flow of the high-temperature organic liquid storage unit flowing to the fuel cell pipeline is adjusted to ensure that the generating capacity of the fuel cell is matched with the electric energy demand of the automobile. In order to guarantee the liquidity and the organic liquid dehydrogenation efficiency, the organic liquid needs to be heated to a high temperature. The organic liquid is heated through the heating control unit, and the low-temperature organic liquid storage unit heats the organic liquid to the temperature above the melting point to guarantee that the liquidity of the organic liquid is not affected; and the high-temperature organic liquid storage unit heats the organic liquid to the optimal reaction temperature for dehydrogenation of the organic liquid, so that the organic liquid enters the fuel cell to reach the optimal reaction temperature. Theheating control unit respectively monitors the temperature of the organic liquid in the low-temperature organic liquid storage unit and the high-temperature organic liquid storage unit, adjusts the power of the electromagnetic heating device, and ensures that the flowability of the low-temperature organic liquid and the temperature accuracy of the high-temperature organic liquid are not affected.

Description

technical field [0001] The present application relates to the field of organic liquid fuel cell vehicles, in particular to an organic liquid heating and heat preservation device for organic liquid fuel cell vehicles. Background technique [0002] At present, the organic liquid used in organic liquid fuel cell vehicles has a relatively high melting point, most of which have a melting point higher than 40°C. During the dehydrogenation process of the organic liquid, the organic liquid needs to be heated to a certain temperature, mostly above 150°C. In order to ensure the fluidity and reaction speed of the organic liquid, it is necessary to heat the organic liquid to a specified temperature and keep it warm. The dehydrogenation reaction of organic liquid is carried out in the fuel cell, and the hydrogen gas produced by the dehydrogenation reaction and oxygen undergo a non-combustion stable reaction to generate electricity. Therefore, in order to ensure that the output power of ...

Problems solved by technology

However, the battery capacity of the car itself is limited. If all organic liquids are heated to the optimum reaction temperature, the overall energy efficiency will inevitably be reduced; if the organic liquid cannot be heated to the optimum reaction temperature, the dehydrogenation efficiency of the organic liquid will inevitably be reduced. , resulting in an incomplete reaction of the organic liquid, which also reduces the overall energy efficiency of the organic liquid
