Description

可侦测浓度的燃料槽
技术领域
本创作是关于一种燃料槽，尤指可侦测浓度的燃料槽。
背景技术
燃料电池(fule cell，FC)是一种利用化学能直接转化成电能的发电装置。与传统发电方式相比，燃料电池具有低污染、低噪音、高能量密度、较高能量转化率等优点，是一种极具发展潜力的电量来源。由于有着上述的优点，其应用范围相当广泛，从便携式电子装置、家用发电、交通工具、航天工业等等领域均可应用。
燃料电池的运作原理依其种类会有些许差异性，若以直接甲醇型燃料电池(Direct Methanol Fuel Cell，DMFC)为例，当甲醇溶液在阳极触媒层进行氧化反应时，会产生氢离子、电子以及二氧化碳，这其中氢离子可通过电解质传递至阴极，而电子则由外部电路传输至负载作工，再传递至阴极。于此同时，供给阴极端的氧气会与氢离子、电子在阴极触媒层进行还原反应，而产生出水。
然而，燃料电池中所使用的甲醇燃料很容易浸透现有的氢离子或质子交换膜(PEM)，而降低燃料电池的电压，降低电池效率，尤其是使用高浓度的甲醇燃料时浸透的情况更为严重。这使得虽然采用高纯度甲醇燃料较能缩小燃料电池的体积，但为避免上述浸透情况发生，只得改采较低浓度的甲醇燃料。
在大多数的情况下，较低浓度的甲醇燃料均是由纯甲醇或高浓度甲醇溶液稀释至较低浓度的甲醇燃料，因此为确实掌握燃料槽流入燃料电池中甲醇浓度，侦测甲醇浓度的侦测装置就会是必须的。
目前侦测甲醇浓度的装置大多装设在燃料电池和燃料混合槽之间的管路中。此种安装方式虽然较为便利，但是因为燃料会快速流过此管路，这使得甲醇浓度侦测装置必须高灵敏度、反应时间短。然而，具有这种特性的甲醇浓度侦测装置大多较为昂贵，进而拉高了燃料电池系统整体的成本。
发明内容
本创作的主要目的在提供一种可侦测浓度的燃料槽，借着直接导出燃料槽的燃料至浓度侦测盒，并借着其内的浓度侦测装置侦测出燃料浓度。
基于上述目的，本创作可侦测浓度的燃料槽可用来储存燃料电池所需的燃料，并作为燃料电池的燃料供应源。在接近燃料储存槽的底部处的信道，可将此燃料流出至浓度侦测盒。在浓度侦测盒中，信号发射组件所发射的信号会穿过此燃料，而让信号接收组件接收到穿过后的信号，这使得浓度侦测组件可基于穿过燃料后的信号变化，而侦测出燃料的燃料浓度。
关于本创作的优点与精神可以通过以下的新型详述及所附附图得到进一步的了解。

具体实施方式
请参阅图1A与图1B，图1A与图1B为本创作可侦测浓度的燃料槽的示意图。如图1A所示，从外观来看，本创作可侦测浓度的燃料槽5主要由燃料储存槽10、浓度侦测盒12所组成，且可作为燃料电池(未描绘)的燃料供应源。第图1B为图1A的剖面图，并可从图1B观察到燃料储存槽10、浓度侦测盒12之间具有侦测浓度信道10a，使供燃料储存槽10中的燃料14通过侦测浓度信道10a直接流出至浓度侦测盒12，并借着如图2所示浓度侦测装置侦测出此燃料14的浓度。浓度侦测盒12的大小远小于燃料储存槽10，也就是其高度可为30mm。
上述侦测浓度信道10a的设置与型态并没有太大的限制，但尽量设置在燃料储存槽10接近底部处，尽量在燃料储存槽10中的燃料14较少时，仍会有燃料14流入浓度侦测盒12。
请参阅图2，图2为本创作浓度侦测盒的示意图。如图2所示，本创作浓度侦测盒12中包含用来侦测燃料浓度的装置，也就是安装在浓度侦测盒12中的信号发射组件16a、信号接收组件16b，但浓度侦测组件18则可装设在浓度侦测盒12内部或外部。
当信号发射组件16a被激活而发射信号时，将会穿过存在于浓度侦测盒12的燃料14，然后会被设置在相对位置的信号接收组件16b可接收此穿过燃料14后的信号。浓度侦测组件18则可基于比较信号发射组件16a所发射的信号、信号接收组件16b所接收的信号，而侦测出燃料14的燃料浓度。
举例来说，若按照燃料浓度正比于燃料14的吸光度(Beer-Lambert法则)，信号接收组件16b则为会发射紫外光的组件，而信号接收组件16b则为相对的接收组件，这使得浓度侦测组件18可按照吸光度来推算出燃料14的燃料浓度。
除了如图1A～图1B所示的单一个储存槽结构，也可由数个甲醇源混合出所需浓度的模式。
请参阅图3，图3为本创作燃料储存槽的示意图。如图3所示，燃料储存槽10进一步包括高浓度燃料储存槽1031、低浓度燃料储存槽1033、燃料混合槽1035，且燃料混合槽1035是分别通过管道100连接于高浓度燃料储存槽1033、低浓度燃料储存槽1033。在燃料混合槽1035则同样具有侦测浓度信道10a，而将燃料14导至浓度侦测盒12，使得浓度侦测盒12内部的浓度侦测装置能够如上述进行侦测。
本创作可采用公知组件来作为上述信号发射组件6a、信号接收组件16b、以及浓度侦测组件18的具体实施组件。本创作的特征在于燃料储存槽10、侦测浓度信道10a、浓度侦测盒12、信号发射组件6a、信号接收组件16b、以及浓度侦测组件18等的配置安排(Configuration)，借此来制作出可侦测浓度的燃料槽5。
本创作可侦测浓度的燃料槽5由于借着直接导出燃料储存槽10的燃料14至浓度侦测盒12，并借着其内的浓度侦测装置侦测出燃料浓度，因此，能以低制作成本来实现出具有浓度侦测功能的燃料槽，此为本创作的有益效果与功效增进的所在。
通过以上较佳具体实施例的详述，是希望能更加清楚描述本创作的特征与精神，而并非以上述所揭露的较佳具体实施例来对本创作的范畴加以限制。相反地，其目的是希望能涵盖各种改变及具相等性的安排于本创作权利要求的保护范围之内。
