The combination of data center and PEMFC has been a promising data center zero-carbon emission solution. However, the relevant experimental studies are very rare and most work only solved the simple electrical coupling. This paper proposed a new in-rack data center servers and PEMFC coupling design scheme considering both the electrical coupling and thermal management coupling of the servers and PEMFC, and built a cabinet prototype for the first time. The complete multi-condition continuous experiment on the PEMFC system fully demonstrates the servers power supply stability of the prototype with the fast tested power response capability of 4.9 kW in 0.1 s. The experiments under rated condition (when the servers power is 5 kW) were conducted and the carbon emission level and efficiency performance of the prototype are analyzed. Under the rated condition, the highest prototype CHP efficiency is 64.1 % while the prototype can provide 41.6 ℃ hot water with 3.04 L·min-1 and the lowest prototype CHP efficiency is 59.8 % while the prototype can provide 61.1 ℃ hot water with 1.33 L·min-1. The prototype maintains the zero-carbon (or negative carbon) emission of servers. The average operation carbon emission rate is -35 g·h-1. Compared with the full grid supporting data center, the power average prototype operation carbon reduction rate is 0.13 g·s-1·kW-1. The application potential of the proposed data center and PEMFC coupling scheme is demonstrated with the prototype experiment results from the advantage of carbon emission and heat recovery potential.

用于具有废热回收的数据中心应用的燃料电池供电机架原型：设计考虑和实验验证


数据中心与质子交换膜燃料电池的结合是一种很有前景的数据中心零碳排放解决方案。然而，相关的实验研究非常少，大多数工作只解决了简单的电耦合。本文提出了一种新型的机架式数据中心服务器与PEMFC耦合设计方案，同时考虑了服务器与PEMFC的电耦合和热管理耦合，并首次搭建了机柜样机。在PEMFC系统上完整的多工况连续实验充分展示了样机的服务器供电稳定性，测试出0.1秒4.9kW的快速功率响应能力。在额定条件下（服务器功率为5 kW）进行实验，分析样机的碳排放水平和效率表现。额定工况下，样机CHP效率最高为64.1 %，样机可提供41.6 ℃热水3.04 L·min-1；样机CHP效率最低为59.8 %，样机可提供61.1 ℃热水1.33 L ·min-1。该原型保持了服务器的零碳（或负碳）排放。平均运营碳排放率为-35 g·h-1。与全电网配套数据中心相比，功率平均样机运行减碳率为0.13 g·s-1·kW-1。原型实验结果证明了所提出的数据中心和质子交换膜燃料电池耦合方案的应用潜力，具有碳排放和热回收潜力的优势。
