Preparation and Mechanism Study of Novel Non-noble-metal Catalysts for Fuel Cells and Water Splitting [PDF]
, 2017 基于燃料电池及水分解制氢的综合能源系统是未来理想的能源循环体系。本论文围绕探索和制备用于燃料电池和电解水系统的新型高效非贵金属电催化剂，并深入探究新型催化剂的催化机理，取得了以下结果： 1.利用廉价的原料经过简单的方法首次制备了一类不含任何过渡金属元素成分的新型低成本非贵金属氧还原催化剂（CPMPDA-NaCl），该催化剂与研究领域内已报导的其他非贵金属ORR催化剂比较表现出最好的催化活性，具有最小的碱性条件ORR理论过电位。该催化剂在0.1MKOH电解液中，极限扩散电流达到4.05mA/cm-2 ...

现货市场下考虑等效循环寿命和温控负荷的综合能源需求响应运行策略
Gaoya dianqi随着电网的新能源渗透比例不断上升，电源侧的电量平衡能力愈发不足。在极端气候等负面因素的影响下，容易发生源荷两侧电量不平衡的现象，其造成的电量缺口严重影响系统的安全稳定运行。综合能源系统内能源耦合程度高、互补性强、调节裕度大，能为电网提供优质需求响应服务，从而有效缓解系统电量平衡问题。针对综合能源系统内各类可调性资源的性质，提出一种现货市场下考虑等效循环寿命和温控负荷的综合能源需求响应运行模型，并重点分析了现货市场出清收益、等效循环寿命、温控负荷、阶梯碳交易对运行策略的影响。通过算例结果证明 ...
