This study proposes an optimal model to design and simulate the proton exchange membrane fuel cell (PEMFC) systems. The purpose of this paper is to present an improved version of seagull optimization algorithm for optimal parameter identification of the PEMFC stacks. The new algorithm uses the...

With the remarkable growth of natural gas consumption and the development of renewable energy worldwide in recent years, the penetration capacity of gas-fired generators and uncertain renewable energy has significantly become larger, which poses a great challenge to the reliable and economic...

Recently, the application of the proton exchange membrane fuel cells (PEMFCs) is extensively increasing as a popular renewable energy source. PEMFCs need low temperature for the operation along with high power density and easy implementation ability. These characteristics turned them into the...

Alkali metal Na is beneficial to the performance of CuInGaSSe thin film solar cells. This work studies the addition and optimization of a sputtering SiO 2 barrier layer on the SLG to optimize the Na content that diffuses into the absorber layer from the SLG. The resulting Se content and...
