In passive transport, substances (e.g. ions and solutes) move across a membrane from a region of their higher concentration to a region of their lower concentration. The movement is described as downhill. Because of this, cellular energy (e.g. ATP) is not required as it is in active tr...
Passive:An Passive transport, also known as passive diffusion, is the process by which molecules or ions move across a cell membrane along their concentration gradient, from an area of higher concentration to an area of lower concentration, without the need for cellular energy expenditure. Interesti...

For the same cell volume, such diluted methanol storage reduces the energy density and so shortens operating time remarkably. In recent work, a spring-driven fuel supply mechanism was introduced in the DMFC system design to save on internal power consumption [18]. To improve on the low power ...
