【具体实施方式】
下面结合附图对本发明做进一步详细描述：
参见图1，本发明包括集流板一体化燃料腔体1、膜电极2、密封紧固集流板3。
1.集流板一体化燃料腔体1
本发明提供一种燃料腔体、集流板合为一体的制作方案。为了使燃料电池的结构更加紧凑，实现整个电池的固定不使用螺栓，运用3D打印技术，将第一集流板4和燃料腔体5制成一体，在第一集流板4部分打上足够多的正方形燃料孔6，使燃料能充分接触电极，同时在燃料腔体5四周设计有固定扣槽7，以实现密封和紧固。为了使制作方便，同时满足一些微小尺寸的加工要求，使用三维建模软件建模，第一集流板4部分采用导电3D打印材料打印，完成集流板一体化燃料腔体1的制作。
如图2所示，为集流板一体化燃料腔体1，包括燃料腔体5，第一集流板4，正方形燃料孔6，燃料加注孔16，固定扣槽7。由于结构较为复杂，且当尺寸较小时，加工更加困难，故使用三维建模软件构建模型后采用3D打印技术打印模型，同时集流板部分应采用导电的3D打印材料。
2.膜电极2
如图3所示，膜电极2包括第一垫片8、阳极9、离子交换膜10、阴极11、第二垫片12，第二垫片12能有效防止燃料泄露。
3.密封紧固集流板3
密封紧固集流板3主要起固定、密封和集流的作用，第二集流板17部分的制作采用导电3D打印材料，且设计成凸圆结构13，密封紧固集流板上3开有足够多的正方形透气孔14，使空气能充分接触阴极11。同时，在密封紧固集流板3四周上设计有固定搭扣15，配合集流板一体化燃料腔体1的固定扣槽7，实现密封和紧固整个电池。
如图4所示，为密封紧固集流板3，包括第二集流板17、正方形透气孔14、 固定搭扣15。第二集流板17部分的制作采用导电3D打印材料，这样可以起导电集流作用，同时使结构更加简单轻便，密封紧固集流板3上开有足够多的正方形透气孔14，使空气能充分接触阴极。同时，在密封紧固集流板3上设计由多个固定搭扣15，配合集流板一体化燃料腔体1的固定扣槽7，实现密封和紧固整个电池。考虑到扣紧后，由于受力不均，第二集流板17可能变形，故集流板采用凸圆结构13设计，这样可以使得膜电极2受力即接触更加均匀，减小电阻。
本发明还公开了一种被动式直接液体燃料电池的制备方法，具体包括以下步骤：
1)使用三维建模软件建模，采用3D打印技术打印，完成集流板一体化燃料腔体1、密封紧固集流板3的制作；
2)将第一垫片8、阳极9、离子交换膜10、阴极11、第二垫片12依次叠放在集流板一体化燃料腔体1的第一集流板4上，然后把密封紧固集流板3盖在膜电极2上，将固定搭扣15扣进固定扣槽7，实现密封、紧固整个电池，完成整个电池的制作。
以上内容仅为说明本发明的技术思想，不能以此限定本发明的保护范围，凡是按照本发明提出的技术思想，在技术方案基础上所做的任何改动，均落入本发明权利要求书的保护范围之内。
