Abstract
The utility model discloses a but high temperature fuel cell system of quick start. The utility model provides a: a but high temperature fuel cell system of quick start, includes the reformation room, be provided with a plurality of electrical heating pieces in the reformation room, the equidistant setting of a plurality of electrical heating pieces, the electrical heating piece is the carborundum heating plate, be provided with a plurality of ventilation grooves in the reformation room. The utility model provides a rapid heating can be carried out to the reformation room to the scheme for the reformation room reaches the required temperature of reforming reaction fast, has shortened fuel battery's activation time greatly.
Description
Technical field
This utility model relates to high-temperature fuel cell technical field, particularly to a kind of high-temperature fuel cell system capable of fast starting.
Background technology
High-temperature fuel cell system includes the reformer chamber for hydrogen making.Methanol-water needs, through heating vaporization, then through heated reformate, to complete hydrogen production process, whole process be endothermic process, preferably reaction temperature be about 250 degree.Current heating means mainly produce high-temperature gas by fuel combustion, vaporizer and reformer chamber are heated by recycling high-temperature gas, gas is as heat transferring medium, the heat carried due to gas is little, firing rate is slow, and from thermal source farther out with close to the position temperature difference big, easily make reformer chamber be heated uneven, the startup time making reformation hydrogen production high-temperature fuel cell system is relatively slow, and efficiency is the lowest.
Summary of the invention
The deficiency existed for prior art, main purpose of the present utility model is to provide a kind of high-temperature fuel cell system that can quickly start, and its response time is short, length in service life and efficiency high.
For achieving the above object, this utility model provides following technical scheme: a kind of high-temperature fuel cell system capable of fast starting, including reformer chamber, is provided with some electric heating sheets, described some electric heating sheets spaced sets in described reformer chamber.
Preferably, described electric heating sheets is carborundum heating plate.
Preferably, described reformer chamber is provided with some ventilation slots.
This utility model has the advantage that relative to prior art, and fuel cell needs to heat reformer chamber to meet the temperature required for reforming reaction before runtime, so reforming reaction can occurred smoothly to produce hydrogen.Traditional reformer chamber mode of heating generally uses combustor first to burn fuel, utilizes aerator that the heat in combustor is blowed to reformer chamber and heats reformer chamber, but combustor is also required to first carry out preheating could be occurred flameless combustion and produce heat.This mode of heating is relatively time-consuming, and the startup time causing whole fuel cell unit is longer.This utility model is by directly arranging electric heating sheets in reformer chamber, electric heating sheets can generate heat rapidly with direct-electrifying and heat reformer chamber, the temperature enabling to reformer chamber is rapidly achieved the temperature required for reforming reaction, the startup time of fuel cell unit thus with quick start hydrogen production, can be greatly accelerated.Some electric heating sheets spaced sets, so arrange benefit be reformer chamber can heated ratio more uniform, it is ensured that reforming reaction can be carried out efficiently, and fault rate is the least, extends the service life of reformer chamber.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of high-temperature fuel cell system capable of fast starting of the present utility model.
In figure: 1, reformer chamber；2, electric heating sheets；3, ventilation slot.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of high-temperature fuel cell system capable of fast starting, including reformer chamber 1, described reformer chamber 1 is provided with some electric heating sheets 2, described some electric heating sheets 2 spaced sets.
Fuel cell needs to heat to meet to reformer chamber 1 temperature required for reforming reaction before runtime, so reforming reaction can occurred smoothly to produce hydrogen.Traditional reformer chamber 1 mode of heating generally uses combustor first to burn fuel, utilizes aerator that the heat in combustor is blowed to reformer chamber 1 and heats reformer chamber 1, but combustor is also required to first carry out preheating could be occurred flameless combustion and produce heat.This mode of heating is relatively time-consuming, and the startup time causing whole fuel cell unit is longer.This utility model is by directly arranging electric heating sheets 2 in reformer chamber 1, electric heating sheets 2 can generate heat rapidly with direct-electrifying and heat reformer chamber 1, the temperature enabling to reformer chamber 1 is rapidly achieved the temperature required for reforming reaction, the startup time of fuel cell unit thus with quick start hydrogen production, can be greatly accelerated.Some electric heating sheets 2 spaced sets, so arrange benefit be reformer chamber 1 can heated ratio more uniform, it is ensured that reforming reaction can be carried out efficiently, and fault rate is the least, extends the service life of reformer chamber 1.
Further, described electric heating sheets 2 is carborundum heating plate.Because the characteristic such as the heating plate that carbofrax material is made has stable chemical performance, high temperature resistant, heat conductivity is high, thermal coefficient of expansion is little and intensity is high, it is possible to meet the good characteristic required for this utility model.
It addition, described reformer chamber 1 is provided with some ventilation slots 3.The Starting mode of fuel cell unit of the present utility model uses the mode that reformer chamber 1 is directly heated by electric heating sheets 2, and advantage heats rapidly exactly so that the startup time of system is greatly shortened.Operationally, electric heating sheets 2 stops heating, and combustor is running, and the tail gas reacted the most completely in pile burns in Flameless combuster, and the heat of generation blows to reformer chamber 1 by aerator and heats reformer chamber 1.Make fuel cell unit more energy-conserving and environment-protective.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
