“…This corresponds to a total annual of 1400-2300kWh/m²; with the average sunshine duration is more than 300 days per year [1][2][3][4][5][6][7]. Nowadays, renewable energy systems are being utilized extensively to generate electricity due to its positive features [8][9][10][11][12][13]. Through various equipment have been invited to measure the incident solar radiation at a given location, due to high cost of maintenance and the resulting inaccuracies and error has required the development of predictive correlation to estimate solar radiation using whether parameter.…”

“…For MPL characterization, often radiography is used. 53,57,58,[63][64][65][66][67] However, radiography can be highly sensitive to sample orientation, and the boundaries between interfacial regions (CL/MPL/GDL substrate) are not always straightforward to distinguish clearly based on the radiographs. The boundary surfaces are often not perfectly smooth and can undergo movement during PEFC operation.…”

“…Recently, energy has a major role in the establishment of wealth and a key issue factor in economic stabilization [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. The energy demand of the world is sharply increasing with the increasing of world population, urbanization and modernization and is expected to keep rising over the coming years [16][17][18][19][20].…”
