The contact pressure between bipolar plates (BPPs) and a membrane electrode assembly (MEA) has key impact on Proton Exchange Membrane Fuel Cell (PEMFC) performance. However, it is difficult to obtain the combined with operating temperature action via finite element analysis (FEA) model, resulting in limited calculation resources for problem of multiscale thermo-mechanical coupled full-dimension...

Nowadays, the use of renewable energy systems, especially fuel cells, has become very widespread in various applications. Some their most important applications include using electric vehicles and local off-grid power systems. One challenges with cells is slow dynamic response to load changes. In fact, when changes suddenly, cell supplies it a time delay, this can cause disturbances performance...

Integration of a reformer and a proton exchange membrane fuel cell (PEMFC) is problematic due to the presence in the gas from the reforming process of a slight amount of carbon monoxide. Carbon monoxide poisons the catalyst of the proton exchange membrane fuel cell subsequently degrading the fuel cell performance, and necessitating the sublimation of the reaction gas before supplying to fuel ce...

In this paper a nonlinear state observer based on a distributed parameter model is proposed for a proton exchange membrane fuel cell (PEMFC).

To implement the model, a nite element discretisation is performed to take advantage of the boundary conditions of the proble...

The Ni60Nb15Ti15Zr10 glassy alloy was developed as a separator material for a proton exchange membrane fuel cell (PEMFC). The corrosion rate of the glassy alloy in sulfuric acid was approximately 3 digits lower than SUS316L. A precise groove forming of the glassy alloy can be achieved by hot-pressing in the supercooled liquid state. The result of the power generation test of the single cell ass...
