Abstract

The world is at a cusp of major transition to fuel cell technology. Water management is of prime importance in air-breathing fuel cells (ABFCs). Inadequate water management leads to the dehydration or flooding which affects the performance of fuel cell. The paper addresses the issues of water management in ABFC by a novel method. Understanding of flooding and dehydration states is presented through experimental investigations. Experiments are conducted at various operating conditions to identify dehydration, normal or flooding states using easily measurable parameters like cell temperature, voltage and current. Preliminarily, by considering iR drop as a distinguishing parameter, dehydration and flooding operating states are distinguished.

一种用于燃料电池汽车的吸气式燃料电池故障模式运行状态检测的新型诊断技术
世界正处于燃料电池技术重大转型的风口浪尖。水管理在空气呼吸燃料电池(abfc)中至关重要。水处理不当会导致燃料电池脱水或淹水,影响燃料电池的性能。本文用一种新颖的方法解决了ABFC的水管理问题。通过实验研究提出了对水淹和脱水状态的理解。在各种操作条件下进行实验,以识别脱水,正常或浸水状态,使用易于测量的参数,如电池温度,电压和电流。以iR降为判别参数,初步区分了脱水和驱油运行状态。
