Ogni cella a combustibile ha una st

Ogni cella a combustibile ha una struttura a strati, con due elettrodi piani conduttori a struttura porosa separati da un elettrolita, che può essere solido o liquido (acido). Questo materiale viene accuratamente scelto poiché deve possedere delle qualità che stanno alla base del funzionamento di ogni singola cella. Infatti deve essere facilmente attraversabile da alcuni tipi di ioni ed impermeabile alle cariche elettroniche. Gli elettrodi invece fungono uno da anodo, mentre l’altro da catodo, ove hanno luogo le reazioni chimiche principali. Inoltre nella struttura è presente un catalizzatore che provvede all’innesco della reazione, mantenendola ad una velocità adeguata. Infatti la temperatura è relativamente bassa (60-100°C) per cui non si ha abbastanza energia per cui il processo avvenga in automatico. Il catalizzatore è la parte più costosa della struttura, in quanto è composto solitamente da metalli pregiati quali Platino, Rutenio e Palladio. Questo processo quindi può avvenire fino a quando viene fornito, alla cella, il combustibile (idrogeno) e l’ossidante (aria od ossigeno).

each fuel cell has a layered structure, with two electrodes to the porous structure conducting planes separated by an electrolyte, which can be solid or liquid (acid). this material is carefully chosen since it must possess the qualities which are the basis of the functioning of each single cell.in fact must be easily penetrable by some types of ions and impermeable to the electronic charges. instead the electrodes serve as the anode one, while the other as a cathode, where the chemical reactions take place main. also a catalyst is present in the structure that provides the triggering of the reaction, keeping it at an appropriate speed.In fact, the temperature is relatively low (60-100 ° c) for which you do not have enough energy to which the process takes place automatically. the catalyst is the most expensive part of the structure, as it is usually composed of precious metals such as platinum, ruthenium and palladium. this process can then take place until it is supplied, to the cell,the fuel (hydrogen) and the oxidant (air or oxygen).

Each fuel cell has a layered structure, with two electrodes in conductive porous structure planes separated by an electrolyte, which can be solid or liquid (acid). This material is carefully chosen because it must possess the qualities that underlie the operation of each individual cell. It must be easily traversable by certain types of ions and waterproof electronic charges. The electrodes instead serve one to the anode, and the other from the cathode, where chemical reactions take place. Also on the property is a catalyst that will trigger the reaction, keeping it at a proper speed. In fact, the temperature is relatively low (60-100° C) so you do not have enough energy for the process happens automatically. The catalyst is the most expensive part of the structure, as it is usually made from precious metals such as Platinum, ruthenium and Palladium. This process can take place until the cell is provided, the fuel (hydrogen) and oxidant (air or oxygen).

This material is carefully chosen because must possess the qualities that are the basis of the operation of every single cell.In fact, it must be easily penetrated by some types of ions and impermeable to electron charges. The electrodes instead act as an anode, while the other as the cathode, where they place the chemical reactions main. Also in the structure and present a catalyst which is responsible for the initiation of the reaction, keeping it at a suitable speed.In fact, the temperature is relatively low (60-100 °C) for which you do not have enough energy for which the process occurs automatically. The catalyst is the most expensive part of the structure, since it is usually made from precious metals such as platinum, ruthenium and palladium. This process then may be up to when it is supplied to the cell,The fuel (hydrogen) and the oxidant (air or oxygen).
