Description

燃料电池系统 The fuel cell system

技术领域 FIELD

[0001] 本发明关于一种燃料电池,特别是关于一种温场均布的燃料电池系统。 [0001] The present invention relates to a fuel cell, particularly to a uniform temperature field of the fuel cell system. 背景技术[0002] 燃料电池(Fuel Cell) 一种将燃料(如氢气、甲醇等)及氧气经由电化学反应而产生电能的发电装置。 [0002] The fuel cell (Fuel Cell) A fuel (such as hydrogen, methanol, etc.) and oxygen gas generated through an electrochemical reaction of the electricity plant. 其常见的种类一般区分为质子交换膜燃料电池(Proton Exchange Membrane Fuel Cell,或称Polymer Electrolyte MembraneFuel Cell,缩写为PEMFC,亦称为PEM)或直接甲醇燃料电池(Direct MethanolFuel Cell,缩写为DMFC)。 The common species is generally classified into proton exchange membrane fuel cell (Proton Exchange Membrane Fuel Cell, also known as Polymer Electrolyte MembraneFuel Cell, abbreviated as PEMFC, also known as PEM) or a direct methanol fuel cells (Direct MethanolFuel Cell, abbreviated as DMFC).

[0003] 直接甲醇燃料电池的膜电极组件(Membrane Electrode Assemble,缩写为MEA)包括阳极表面及阴极表面,其阴极燃料为氧气。 The membrane electrode assembly [0003] Direct methanol fuel cells (Membrane Electrode Assemble, abbreviated as MEA) comprising an anode surface and a cathode surface of a cathode of the fuel to oxygen. 氧气的供应可为纯氧气或利用空气中的氧气, 由导风装置(如泵浦或风扇)导入空气至该阴极表面,导风装置除了能供应燃料电池反应所需的氧气之外,亦能同时将燃料电池反应时所产生的热能带出。 The supply of oxygen may be pure oxygen or with oxygen in the air introduced by the air guide means (such as a pump or fan) of air to the cathode surface, the air guide means in addition to supplying the oxygen required for fuel cell reactions outside, can also while the thermal energy generated by the fuel cell out of the reaction.

[0004] 请参阅图1及图2所示,常规平面堆叠型燃料电池组100包括壳体1、导风装置2 以及多个燃料电池模块3。 [0004] Please refer to FIGS. 1 and 2, a conventional flat-stack type fuel cell stack 100 includes a housing 1, a plurality of air guiding device 2 and the fuel cell module 3. 其中,壳体1包括出气口区11及进气口区12,两者分别开设在壳体1的相对的侧壁上。 Wherein the housing includes an outlet region 11 and the intake port region 12, respectively provided on both opposing side walls of the housing 1.

[0005] 导风装置2(例如轴流风扇)配置于出气口区11。 [0005] The air guiding device 2 (e.g., axial-flow fan) disposed in the air outlet area 11. 各个燃料电池模块3呈平板结构型态,相邻的燃料电池模块3之间具有预定间隔。 Each fuel cell module 3 has a flat plate type structure, adjacent fuel cell module 3 having a predetermined spacing between. 每一个燃料电池模块3包括多个沿延伸方向I间隔排列的膜电极组件31a、31b、31c,各个膜电极组件31a、31b、31c由框体33予以定位。 Each of the fuel cell module 3 includes a membrane electrode assembly of a plurality of I spaced in the extending direction 31a, 31b, 31c, each of the membrane electrode assembly 31a, 31b, 31c to be positioned by the frame 33. 各个膜电极组件31a、31b、31c的阴极表面32暴露于该壳体1的容置空间13。 Each of the membrane electrode assembly 31a, 31b, 31c of the cathode surface 32 is exposed to the accommodating space 13 of the housing 1. 延伸方向I平行于导风装置2的转轴的方向。 Extending in a direction parallel to the I direction of the rotation shaft of the air guide means 2.

[0006] 当导风装置2运转时,导入气流AI经由进气口区12沿延伸方向I导入至壳体1 的容置空间13,然后导入气流AI顺序地流经各个膜电极组件31a、31b、31c的阴极表面32, 再由出气口区11导出一导出气流A0。 [0006] When the operation of the wind guide means 2, the air flow introduced through the intake port AI region 12 in the extending direction I introduced into the accommodating space 13 of the housing 1, and are sequentially introduced into the gas flow flowing through the respective AI membrane electrode assemblies 31a, 31b , the surface 31c of the cathode 32, and then deriving a derived gas flow from the outlet region 11 A0.

[0007] 对燃料电池而言,膜电极组件反应的温度越高,其发电的效能越高,但若在同一燃料电池系统中,各个膜电极组件彼此温差过大,造成温场不均一的状况时,除影响到操作效能之外,亦影响到膜电极组件的寿命。 [0007] The fuel cell, the higher the reaction temperature of the membrane electrode assembly, the higher the power generation performance, but if the same fuel cell system, the temperature difference between each of the membrane electrode assemblies to each other is too large, resulting in a nonuniform temperature field conditions when, in addition to affecting the operational effectiveness addition, also affect the life of the membrane electrode assembly. 然而,常规平面堆叠型燃料电池组100将导风装置2装设于壳体1的两相对侧壁,使得导入气流AI沿膜电极组件31a、31b、31c间隔排列的延伸方向I流动,单向的导入气流AI流经每一膜电极组件的阴极表面后,其上游(即邻近进气口区12)热量累积至下游(即邻近出气口区11),而使得下游的空气温度越高,使位于下游的膜电极组件31b、31c温度亦累积越高,故造成各个膜电极组件的温场不一,致使各个膜电极组件的发电量不同,且单位面积的发电密度亦为不同,此一状况对于燃料电池的电性特性及发电效能均为不利。 However, conventional planar stack type fuel cell stack 100 is mounted on the air guide means of two opposite side walls of the housing 1 2, such that the gas flow introduced into the membrane electrode assembly in AI 31a, extending in the direction 31b, 31c spaced I flows, the one-way after introducing the cathode surface AI stream flowing through each of the membrane electrode assembly, which is upstream (i.e., adjacent the air inlet region 12) to a downstream heat buildup (i.e., adjacent the outlet region 11), such that the higher the temperature of the air downstream of the located downstream of the membrane electrode assembly 31b, 31c also accumulate higher temperature, so resulting in temperature field of each membrane electrode assembly varies, resulting in different power generation amount of each membrane electrode assembly, and the power density per unit area is also different, this condition for the electrical characteristics of the fuel cell power generation performance and are unfavorable. 且也会造成各个膜电极组件的寿命不同。 And will result in different life of each membrane electrode assembly.

[0008] 再者,燃料电池组由各膜电极组件的阳极燃料(例如:甲醇)与膜电极组件表面的催化剂反应解离产生氢离子与电子,而阳极反应生成的氢离子与电子在阴极与空气中的氧气反应生成水,使壳体10的出气口区11的导风装置2所产生的气流再将阴极的水带走。 [0008] Further, the fuel anode of the fuel cell stack each membrane electrode assembly (eg: methanol) catalyst to the reaction surface of the membrane electrode assembly dissociates hydrogen ions and electrons, the anode reaction generates hydrogen ions and electrons at the cathode It reacts with oxygen in air to generate water, so that the housing 10 of the outlet region 11 of the air guide device 2 produced water stream and then a cathode away. 若各个膜电极组件产生反应的温场不均一,风流越下游则空气所含的水气越多,其阴极生成物越接近饱和越不易排出,造成“水满溢”(Flooding)的问题,而降低膜电极组件的寿命。 If a non-uniform temperature field in each of the membrane electrode assembly react, the air flow downstream of the air contained more moisture, which is closer to the cathode product more difficult to discharge saturated, resulting in "water overflowing" (Flooding) problem, and reduced life of the membrane electrode assembly.

[0009] 再就常规平面堆叠型燃料电池组的流阻过高,故风扇需维持在较高的转速下运转,如此增加了系统的用电负荷,且风扇在高速及高负荷运转状况下,将产生更大的噪音。 [0009] and then to the high flow resistance of conventional planar stack type fuel cell stack, so that the need to maintain the fan at high speed operation, thus increasing the load on the system power, and the fan at high speed and high load operation condition, will produce more noise.

[0010] 发明内容[0011] 本发明的目的是提供一种燃料电池系统,以解决已知的问题。 [0010] SUMMARY [0011] The object of the present invention is to provide a fuel cell system, in order to solve known problems.
