Fuel cell is a kind of power generation device, but it is not like a normal non-rechargeable battery and discarded when used up, nor is it like a rechargeable battery. To maintain its electricity, the fuel required is “hydrogen”, and this is why it is classified as a new energy source. Principle of fuel cells...

At present, hydrogen production mainly contains four processes and technologies:1. Electrolysis of water; 2. Fossil fuels; 3. Industrial by-products; 4. Biomass. Electrolysis of water can directly obtain fuel hydrogen without CO, but its high cost is not conducive to the widespread promotion of this technology. Although the cost of the three types of production technologies...

Obecnie, w PEMEC, warstwa dyfuzyjna cieczy/gazu (LGDL) z tytanowego filcu znajduje się pomiędzy warstwą katalizatora (CL) a warstwą zbierającą prąd z polem przepływu. Zadaniem tytanowego filcu LGDL jest transport elektronów, ciepła oraz reagentów/produktów do i z CL przy minimalnych stratach prądowych, termicznych i płynowych....
