Abstract<\/h3>\n

This study focuses on the development of new cathodes for hydrogen production by electrolysis of water. The experiments are carried out in 20g\/l NaOH solution at 25\u00b0C using cathode alloys type (Zn90%Me10%) (mass %) where Me is Iron (Fe), Copper (Cu), Chromium (Cr), and Cobalt (Co). Homogenized alloys were compacted and heat-treated under an ambient atmosphere. The test of cathode\u2019s production shows that the volume of gas increases continuously with increasing input power, and the productivity of various electrodes follows the trend (Zn90%Cr10%)> (Zn90%Cu10%)> (Zn90%Co10%)> (Zn90%Fe10%).<\/p>\n

Cette \u00e9tude porte sur le d\u00e9veloppement de nouvelles cathodes pour la production d’hydrog\u00e8ne par \u00e9lectrolyse d\u2019eau. Les exp\u00e9riences ont \u00e9t\u00e9 r\u00e9alis\u00e9es \u00e0 25\u00b0C en utilisant une solution de NaOH \u00e0 20g\/l et des alliages cathodiques type (Zn90%Me10%) (% massique) o\u00f9 Me repr\u00e9sente soit le Fer (Fe), le Cuivre (Cu), le Chrome (Cr) ou le Cobalt (Co). Les alliages homog\u00e9n\u00e9is\u00e9s ont \u00e9t\u00e9 compact\u00e9s et trait\u00e9s thermiquement sous conditions atmosph\u00e9riques ambiantes. Le test de production des cathodes montre que le volume de gaz augmente avec l’augmentation de la puissance d’entr\u00e9e, et la productivit\u00e9 des diff\u00e9rentes \u00e9lectrodes suit la tendance (Zn90%Cr10%)> (Zn90%Cu10%)> (Zn90%Co10%)> (Zn90%Fe10%).<\/p>\n[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”20px” equal_height=”yes” content_placement=”middle” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” advanced_gradient_angle=”0″ overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none” gradient_type=”default” shape_type=””][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_spacing=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” tablet_text_alignment=”default” phone_text_alignment=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][vc_column_text]\n
