Water cluster characteristics of fuel cell gas diffusion layers with artificial microporous layer crack dilation

Coaly Graphite as an Eco-Friendly Material in the Microporous Layer of Proton Exchange Membrane Fuel Cells

“…Additionally, the CB + 50% CG + GO MPL is expected to be stable in the long term. First, its raw materials, CB, CG, and GO, are stable under air and humidified conditions, which have been proven by the literature. ,,, Second, GO can mitigate crack formation (Figure c compared with a), which further improves mechanical strength and long-term stability. − Third, a recent report has shown that 1 μg cm –2 GO acts as the buffer layer for PEM fuel cells and improves the stability of the catalyst, while it is also the case here, and is expected to improve the stability of the catalyst at the MPL-CL interface. So, it is expected that this structure can be stable during PEM fuel cell operation.…”

The value of ammonia towards integrated power and heat system decarbonisation

“…Considering hydrogen, beyond SMRCCS and BGCCS it can be produced via Water Electrolysis (WE) 88,89 . Regarding WE, a plethora of literature works investigates their operation consuming electricity exclusively from RES 90 . Moreover, Supercritical's "GreenNH 3 " project for green ammonia production in the UK investigates green hydrogen production using wind energy through power purchase agreement 91 .…”

Designing proton exchange membrane fuel cells with high specific power density

“…127 Therefore, optimizing the design of the GDLs is an important way to improve the performance of PEMFCs. 128,129 Currently, the GDL materials used by most mainstream PEMFC manufacturers usually comprise a microporous layer coated on a carbon ber paper substrate. 130 The carbon paper layer and microporous layer are closely related, and their material and structural parameters (such as thickness, graphitization degree, pore size and pore size distribution, hydrophilicity, and hydrophobicity) have a direct impact on the water gas transport and conductive thermal conductivity of the GDLs, thereby determining the comprehensive performance of the GDLs.…”
