下面参考图1描述根据本申请实施例的燃料供给系统100。
如图1所示，根据本申请实施例的燃料电池的燃料供给系统100，包括：液态燃料瓶1、泵池2、供给管路3和增压管路4。
参照图1,，液态燃料瓶1具有出液口以及增压气相口；泵池2具有用于对泵池2进行增压的增压泵201，泵池2的进口与出液口连通；供给管路3与泵池2的出口连通，另一端与燃料电池的燃料进口连通；增压管路4的一端与增压泵201的泵出口连通，另一端与增压气相口连通；其中液态燃料瓶1的压力小于液态燃料的临界压力。
液态燃料瓶1的出液口与泵池2连通，泵池2可以存放流出液态燃料瓶1的燃料，增压泵201设置在泵池2内，可以对泵池2内的燃料进行增压，并将增压后的燃料供给至供给管路3，供给管路3将增压后可以满足燃料电池供气压力需求的汽化燃料供给至燃料电池的燃料进口；在液态燃料瓶1需要进行增压，以确保液态燃料瓶1与泵池2之间的压力差，使液态燃料瓶1可以稳定地进行燃料供给时，可以通过增压泵201向液态燃料瓶1供给加压后的燃料，以实现液态燃料瓶1的加压。
根据本申请实施例的燃料电池的燃料供给系统100，通过设置泵池2，并使液态燃料瓶1的压力小于液态燃料的临界压力，一方面，可以确保供气压力满足燃料电池的使用需求；另一方面，可以避免液态燃料瓶1内的压力以及温度均超出临界值，产生超临界状态的燃料，以降低供气压力以及液态燃料瓶1的压力调整难度，使液态燃料瓶1的内部压力调整更加简单、方便。
如图1所示，根据本申请的一些实施例，泵池2还包括：外壳202、设置在外壳202内的内胆203，增压泵201设置在内胆203内，泵池2的进口和出口均形成在内胆203上。
增压泵201可以使内胆203内的燃料的压力上升，以满足供气压力需求，而增压泵201的出口还可以与增压管路4连通，以通过增压泵201增加液态燃料瓶1内的压力。
在图1所示的具体的实施例中，燃料供给系统100还包括：第一单向阀5，第一单向阀5设置在泵池2的出口上，泵出口与增压管路4、供给管路3以及第一单向阀5连通。
需要指出的是，通过设置第一单向阀5，并使第一单向阀5与供给管路3、增压管路4、泵出口连通。由此，在通过增压泵201对液态燃料瓶1进行增压时，关闭第一单向阀5，可以避免出现回流现象(即避免压力较高的燃料回流到内胆203)，而在内胆203内部压力较高，可以实现对液态燃料瓶1的增压时，可以控制泵池2的出口与增压管路4连通，实现对增压管路4的增压，降低内胆203的压力的同时提高液态燃料瓶1内的压力，确保液态燃料瓶1与内胆203之间的压力差，以提高燃料供给系统100的供给稳定性。
进一步地，泵池2的进口与出液口之间还设置有依次连通的出液阀6以及第二单向阀7。由此，通过出液阀6控制液态燃料瓶1向泵池2进行燃料供给，通过第二单向阀7避免出现燃料回流，以进一步提高燃料供给系统100的工作稳定性。
如图1所示，在一些实施例中，供给管路3包括：依次连通的第三单向阀301、过流阀302、汽化器303、缓冲罐304、稳压阀305以及航空接头306，第三单向阀301与第一单向 阀5连通，航空接头306与燃料进口连通。
这样，在进行燃料供给时，液态燃料从增压泵201流入至第三单向阀301，第三单向阀301避免液态燃料出现回流，过流阀302限制液态燃料流量，避免过流，而汽化器303对液态燃料进行汽化，缓冲罐304对汽化后的气态燃料进行缓冲，缓冲后的气态燃料被稳压后，通过航空接头306输送至燃料电池的燃料进口，以提高燃料供给的稳定性。
其中，缓冲罐304可以根据使用需求选取容积，例如：40L。
在稳压阀305与缓冲罐304之间还设置有并联的缓冲罐压力传感器308和供给管路安全阀309，通过缓冲罐压力传感器308实时检测缓冲罐304内压力，供给管路安全阀309用于在供给管路3压力过大时开启泄压，以提高燃料供给系统100的工作稳定性，而供气压力传感器307设置在稳压阀305与航空接头之间，用于检测供气压力，可以获取供气压力是否满足供气压力需求，并可以反馈至增压泵201以进行调整。
根据本申请的一些实施例，增压管路4包括：依次连通的增压自动阀401、增压器402，增压自动阀401与泵出口、第一单向阀5连通，增压器402与增压气相口连通。
这样，在需要对液态燃料瓶1进行增压时，可以控制泵池2的出口与增压自动阀401、增压器402连通以进行增压，并降低内胆203的压力，实现燃料供给的稳定，或者直接通过增压泵201、增压自动阀401以及增压器402进行增压，实现对液态燃料瓶1的自动增压。
如图1所示，在一些实施例中，液态燃料瓶1还包括：进液口、排放口和抽真空口，燃料供给系统100还包括：加注管路8、防爆阀12以及安全管路，加注管路8与进液口连通，防爆阀12与抽真空口连通，安全管路与排放口或增压管路4连通。
由此，通过加注管路8进行液态燃料的加注，通过安全管路控制燃料供给系统100的安全，通过防爆阀12及时泄压，以确保液态燃料瓶1的使用安全性。
可以在液态燃料瓶1内设置液位计101，便于用户判断液态燃料瓶1内的燃料余量。
参照图1，加注管路8包括：依次连通的第四单向阀801、加注接头802，加注接头802与燃料加注口连通，第四单向阀801与进液口连通。
可以理解的是，安全管路包括：第一安全管路9和第二安全管路10，第一安全管路9与排放口连通，第二安全管路10与增压管路4连通。
也就是说，第一安全管路9在液态燃料瓶1内压力过高或出现故障时，进行液态燃料瓶1的排空，而第二安全管路10可以在增压管路4出现故障时，进行排空处理，以提高燃料供给系统100的使用安全性。
第一安全管路9具有第一级安全阀901，第一级安全阀901开启则对应排放口与外界连通，实现排放，第二安全管路10包括：并联的手动泄压阀1002和第二级安全阀1001，可以通过手动泄压阀1002或第二级安全阀1001进行泄压，以避免增压管路4出现故障导致的安全事故，提高安全性。
第二安全管路10、增压管路4还通过回气管路11与回气口1102连通。
回气管路11具有回气阀1101，回气阀1101与增压管路4连通，可以控制液态燃料瓶1回气，以提高安全性。
在图1所示的具体的实施例中，燃料供给系统100还包括：压力检测管路13，压力检测管理包括：压力表阀1301、燃料瓶压力传感器1302、燃料瓶压力表1303，压力表阀1301与手动泄压阀1002并联设置，压力表阀1301的出口与燃料瓶压力传感器1302、燃料瓶压力表1303连通，燃料瓶压力传感器1302实时检测液态燃料瓶1的压力，压力表实时体现出压力数值，压力表便于用户观测压力，而燃料瓶压力传感器1302与控制器电信号连接，当液态燃料瓶1压力过高或过低时，均可以反馈给控制器，控制器控制对应的安全管路或增压泵201工作，以实现燃料供给系统100的动态平衡，提高燃料供给系统100的工作稳定性以及安全性。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本申请的实施例，本领域的普通技术人员可以理解：在不脱离本申请的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本申请的范围由权利要求及其等同物限定。
