PHM-oriented Degradation Indicators for Batteries and Fuel Cells

What are batteries, fuel cells, and supercapacitors?

Electrochemical energy conversion devices are pervasive in our daily lives. Batteries, fuel cells and supercapacitors belong to the same family of energy conversion devices. They are all based on the fundamentals of electrochemical thermodynamics and kinetics. All three are needed to service the wide energy requirements of various devices and systems. Neither batteries, fuel cells nor electroch...

PHM of Proton-Exchange Membrane Fuel Cells - A review

Fuel Cell (FC) systems are promising power-generation sources that are more and more presented as a good alternative to current energy converters such as internal combustion engines. They suffer however from insufficient durability for stationary and transport applications, and lifetime may be improved. A greater understanding of underlying wearing processes is needed in order to improve this t...

Demonstration Method for PHM-Oriented Testability Design

The development of PHM propels the combination of design for testability and relevant PHM technology, which leads a need for the demonstration of PHM-oriented testability design. The paper mainly introduces the evaluation and demonstration method ranging from the design phase to the demonstration phase. Firstly, the index set to be evaluated is established according to the feature of the PHM-or...

Comparison between Batteries and Fuel Cells for Photovoltaic System Backup

Batteries and fuel cells contain a great potential to back up severe photovoltaic power fluctuations under inclement weather conditions. In this paper comparison between batteries and fuel cells is carried out in detail only for their PV power backup options, so their common attributes and different attributes is discussed. Then, the common and different attributes are compared; accordingly, th...
