In other words, if you already have the battery, the fuel cell becomes worse than redundant.TALewis said:Ultimately, in the "hydrogen economy," hydrogen becomes like a battery: a way of storing and transporting energy.
Probably the least complicated way of doing it, but I don't think this will translate to self serve stations where old ladies can fill their own cars up without a lot of streamlining.Cliff_J said:Hydrogen is transferred with pressurized hoses and couplings.Cliff

Is the hydrogen in this case merely under pressure, liquid, or what? How many miles can they get on a "fillup"?
Robot arm is good. General acceptance will be highly dependent on convenience.Cliff_J said:The system like BMW was using for methanol on their 7-series car would work with the robotic arm to do the refueling duty.
Did you catch about the 5 minute warm up time? That's a bug they'll have to work out.EDIT: Just found this via google:

Peavy discusses the pros and cons of hydrides from a lot of angles without coming to a clear conclusion about how to translate them to use in consumer vehicles. The material itself is problematic because it loses the proper consistancy to hold the hydrogen after so many uses. It starts off granulated and eventually becomes powdery. My impression, though, (just from that one book,) is that it seems to have more promise than high pressure or liquid. He suggests that the powder may have to be exchanged for granules every so often at a special station the way people get their oil changed.That is very high pressures at 7000psi. I think I'd rather have the hydride storage.
A hydrogen fuel cell is a device that converts chemical energy from hydrogen into electricity. It works by using a chemical reaction between hydrogen and oxygen to generate an electric current. The hydrogen is fed into one side of the cell, while oxygen is fed into the other. The two reactants then go through a series of reactions, producing water and releasing energy in the form of electricity.
There are several benefits to using a hydrogen fuel cell. Firstly, it is a clean and renewable source of energy, as the only byproduct is water. It is also more efficient than traditional combustion engines, with a higher energy-to-weight ratio. Additionally, hydrogen fuel cells are quiet and have low maintenance costs.
The design of a hydrogen fuel cell is optimized for efficiency in several ways. Firstly, the electrodes and electrolyte are carefully chosen to maximize the rate of the chemical reaction. The flow of reactants and products is also optimized to ensure efficient use of materials. Additionally, the design may incorporate features such as heat exchangers to capture and utilize waste heat, further increasing efficiency.
One of the main challenges in designing a hydrogen fuel cell is the cost of materials. Currently, the materials used in fuel cells, such as platinum, are expensive and can limit widespread adoption. The storage and transportation of hydrogen also present challenges, as it is a highly flammable gas. Finally, ensuring the durability and longevity of fuel cells is an ongoing challenge.
Hydrogen fuel cells have a wide range of potential applications in various industries. They can be used in transportation, such as in cars, buses, and trains, as well as in stationary power generation for buildings and homes. They also have potential uses in aerospace, marine, and military applications. Research is ongoing to explore the possibilities of implementing hydrogen fuel cells in other industries as well.
