Fuel cells are a promising technology for use as a source of heat and electricity for buildings, and as an electrical power source for electric motors propelling vehicles. Fuel cells operate best on pure hydrogen. But fuels like natural gas, methanol, or even gasoline can be reformed to produce the hydrogen required for fuel cells. Some fuel cells even can be fueled directly with methanol, without using a reformer.
Answer 2: Chlorophyll is a green pigment that gives most plants their color.The reason that it is green is because it absorbs other colors of light such as red and blue, so in a way the green light is reflected out since the pigment does not absorb it.and plants (and plants in the ocean, called algae) have a lot of chlorophyll-a pigment because it is essential to photosynthesis, but they also have other pigments, called accessory pigments, that help them absorb light.
  Yes, because chlorophyll gives foliage the green pigment needed for photosynthesis to occurr. It is needed because with it there are chloroplasts in the foliage which ab â¦ sorb the sunlight producing oxygen for us life forms.hlorophyll is a green pigment, that can be found in most plants. It absorbs sun light, the energy source for Photosynthesis, and is essential for plants to make food.
