The positive terminal of the solar cell, the cathode, is often coated with a catalytic material for electron transfer. In most cases this is in the form of trace amounts of platinum. Since a very small quantity of catalyst is needed, the electrode remains transparent, provided the substrate is transparent as well.

The sintering behaviour of the individual layers is analysed and partly adjusted so the multi-layer support can be co-fired together with the YSZ electrolyte layer. In the oxidized state, four-layer, porosity graded anode supported half-cells with a dense YSZ electrolyte are demonstrated. The possibility of capture and storage of carbon dioxide in various media like amines, zeolites, and metal organic frameworks, as well as in geological systems, oceans, and by mineral carbonation has been technologically considered. The capture and storage of carbon dioxide emissions can also be considered as a valuable resource because CO2 can be catalytically converted into industrially relevant chemicals and fuels.

The most accepted mechanism of NRR contains associative and dissociative paths. Firstly, the nitrogen molecules are adsorbed on the catalyst surface and then the hydrogenation process proceeds. As with CRR, the NRR involves multiple intermediates, and the HER is a major competing reaction, making selectivity a great challenge. In accordance with the general features of this invention the .anode hook and sus pending bar are formed with surfaces which provide for contact between them at a point or points of small area with a pressure equal to the full weight of the suspended anode.

The electrodes are of finely divided, porous carbon, which provide a great charge density. The voltage is lower than for a conventional capacitor, while the time for charge-discharge is longer because ions move and reorientate more slowly than electrons. Carbon materials and carbon nanomaterials are applied in many fuel cell technologies, which are being extensively explored. On the other hand, in the direct carbon fuel cell , the overall investment is relatively small, and considerable effort is required to take this technology to the pre-commercialization stage. For this reason, and the fact that carbons, namely carbon anodes, play a key role in this system, we have decided to analyse this fuel cell here.
