Real-Time Control of Gas Supply System for a PEMFC Cold-Start Based on the MADDPG Algorithm
Energies, 2023 During the cold-start process of a PEMFC, the supply of air and hydrogen in the gas supply system has a great influence on the cold-start performance. The cold-start of a PEMFC is a complex nonlinear coupling process, and the traditional control strategy

Mechanical Engineering, 2014 This article explains how electrostatic discharge from oil can destroy sensitive and crucial engine components. All thermomechanical power systems contain a dielectric fluid – namely the circulating lubricant oil – where its circulation can create friction and cause a static electric charge to build up.

Dynamic models for start-up operations of batch distillation columns with experimental validation [PDF]
, 2004 The simulation of batch distillation columns during start-up operations is a very challenging modelling problem because of the complex dynamic behaviour. Only few rigorous models for distillation columns start-up are available in literature and generally

Cold start performance analysis of PEMFC with different assisted heating strategies
Case Studies in Thermal EngineeringLarge-scale use of proton exchange membrane fuel cell (PEMFC) is restricted by the challenge of cold start. A three-dimensional, transient, multiphase flow cold-start model is established to investigate the effects of different assisted heating ...

Deuterium burning in objects forming via the core accretion scenario - Brown dwarfs or planets?
, 2012 Aims. Our aim is to study deuterium burning in objects forming according to the core accretion scenario in the hot and cold start assumption and what minimum deuterium burning mass limit is found for these objects.
