For the past decade, research on vertical axis wind turbines (VAWTs) has garnered immense interest due to their omnidirectional characteristic, especially the lift-type VAWT. The H-rotor …
BPPs are the foundation of fuel cells, making up 80% of a fuel cell''s weight, 50%–65% of its volume, and 40% of its total cost. 6,7 This makes it crucial to find a material that is lightweight, inexpensive, and easy to manufacture. Some other requirements for the plates include high mechanical strength, high electrical and thermal conductivity, ability to …
Thermal energy storage represents a cost-effective method for overcoming some of the issues facing a transition to renewable energy. To overcome the problem of low solid thermal conductivity which limits the energy store discharge rate, high conductivity composites should be optimised from a steady state and dynamic perspective.
Heat exchanger plays a crucial role in the functioning of chemical industries, diary and food processing industries, and thermal plants. The enhancements in heat exchangers are mainly aimed at minimizing the energy consumption. An efficient heat exchanger is one that provides high heat transfer rate with minimum pumping power at …
Flat plate solar energy collectors are one of the oldest and most successful applications of solar energy utilization. They are usually constructed from transparent glazing material ...
Bipolar/end plate is one of the most important and costliest components of the fuel cell stack and accounts to more than 80% of the total weight of the stack. In the …
Liquid cooling strategies such as cold plates have been widely employed as an effective approach for battery thermal management systems (BTMS) due to their high cooling capacity and low power consumption. The structural design of the cold plates is the key factor that directly determines the thermal performance of the liquid cooling system. …

In this paper, a three-dimensional transient model is established on the basis of Newton''s second law of motion, Hooke''s law, and conservation of energy to analyze the stress and displacement of the end plate under different stack assembling conditions prior to operation such as the thickness of the end plate and the position and …
A study of PEMFC end plate design by structural analysis was presented by Dey et al. [21]. They aimed to study the influence of cell geometry, bolt configuration, …
1. Introduction. Fossil fuels (e.g. coal, oil, natural gas) still dominate the main energy supply mode worldwide nowadays [1, 2].Excessive use of fossil fuels containing elements of carbon, sulfur, and nitrogen will inevitably lead to severe environmental issues, the representative of which is the global warming [3, 4].To address with the crisis, many …
Design Guide 39: End-Plate Moment Connections
This study provides a framework for future end plate design of fuel cells. 1. Introduction. Polymer electrolyte membrane fuel cell (PEMFC) is one of the promising technologies for electrical power generation. Presently, PEMFCs utilize solid polymer membrane as an …
That is, the higher the energy storage plate, the stronger the natural convection in the liquid PCM. Therefore, the energy storage rate in B1 was larger than that in B4. The specific melting time of PCM in LHTES plate with different aspect ratios is shown in Fig. 6. The time required for PCM to melt completely in B5 (3:1) was the shortest ...
The endplate plays an important role in the performance and durability of fuel cell stacks, and also to mass power density. Aiming at a lightweight endplate and uniform deflection of the endplate, the purpose of this study is to model the endplate including the supply, discharge ports and the distribution manifolds. The stress and …
