Abstract
Hydrogen fuel cells have long been regarded as a more environmentally friendly alternative to traditional fossil fuels. Ethanol steam reforming (ESR) is a promising long-term, safe method of producing carbon-neutral hydrogen. ESR products are (CeCO2) support generate hydrogen (H2) with byproducts such as carbon dioxide (CO2) and carbon monoxide (CO). The researchers are interested in the quantification and estimation of syngas components. The current article introduces the Johnsen index-based measure in partial least squares (PLS) for predicting ESR products with cube, polyhydra, and rod morphologies, based on FTIR. The proposed method makes use of existing filter measures such as loading weights, variable importance on projection, and significant correlation. The proposed PLS measures based on the Johnsen index outperform the existing methods for predicting ESR products based on FTIR spectroscopic data. For (H2) conversion percent prediction with cube and polyhedra morphologies, the functional compounds (C-O), (C=O), (CH), and (C-H,=CH2) are common. Similarly, the functional compound (s-RCH=CHR) is frequently used for (H2) conversion percent prediction with polyhedra and rod morphologies. Moreover, on simulated data, the proposed Johnsen measure in PLS demonstrates higher sensitivity and accuracy. Furthermore, the proposed Johnsen measure in PLS identifies influential wavenumbers that map over the functional compounds.

Summary
A fuel cell is an electrochemical cell that converts the chemical energy of the fuel and an oxidising agent into electricity. This conversion typically makes use of hydrogen as a fuel and oxygen as an oxidising agent. Hydrogen fuel cells have long been regarded as a more environmentally friendly alternative to traditional fossil fuels. Because water is the only direct byproduct of their energy production, they will significantly reduce waste and man-made greenhouse gases by oxidising molecular hydrogen [1,2]. Among non-fossil feedstocks such as ethanol, methanol, and others, ethanol has many advantages as a chemical (H2 ) source for fuel cells due to its storage capabilities, ease of handling, and stable transportation due to its low toxicity and volatility. ESR primarily generates hydrogen (H2 ), with byproducts such as carbon dioxide (CO2 ), carbon monoxide (CO), and methane (CH4 )
