Research on Coordinated Control Strategy of Fuel Cell Anode Pressure and Flow Based on Deep Reinforcement Learning

Wei Lu
In view of the control problem of hydrogen pressure and flow coupling in the anode subsystem of the Proton Exchange Membrane Fuel Cell (PEMFC) under dynamic load conditions, this paper proposes an intelligent control framework based on the deep deterministic policy gradient (DDPG) algorithm. Firstly, a dynamic model of the fuel cell anode system is established to transform the multivariable coupling control problem into a reinforcement learning state space; secondly, a multi-objective reward fun...

The Regulatory Effect of Salicylic Acid on the Physiology of Mentha under Aluminum Stress and Its Alleviation of DNA Damage

Jiayi He,Xiu Wu
Aluminum stress is an important factor limiting plant growth in acidic soil, and has significant effects on the growth, development and physiological metabolism of Mentha canadensis. However, the exogenous addition of Salicylic acid significantly alleviated the negative effects of aluminum stress on Mentha canadensis. In order to reveal the mechanism of Salicylic acid in alleviating aluminum stress, this study used the different concentrations of Mentha canadensis plan...

Calculation and Study on the Exposure Buildup Factor of Type 316 Stainless Steel

Dan Li, Yinglei Guo, Guangxi Wang, Liangquan Ge
Buildup factor is an important parameter in the design of a radiation shielding system. As a manufacturing material commonly used for nuclear equipment, type 316 stainless steel is selected as the research object of this article. Exposure geometric progression fitting parameters and the corresponding exposure buildup factor (EBF) are calculated for type 316 stainless steel in the photon energy range of 0.015 MeV - 15 MeV, as well as penetration depth up to 40 mean-free-paths (mfp), and studied a...
