interesting! soon in our (electric) vehicles?

[Gaston]

The capacity is impressive

Too bad the chosen technology has such a poor performance

What do you mean Gaston! 97% yield don't believe it? Neither do I!

... solid phase storage already published here in several places:

It works, but for the yield ... (it depends on what yield we are talking about, huh, under what conditions, etc ...)

Much better with liquid phase storage (which only uses iron for catalysis):

> 60% remedy announced by EPFL.

Otherwise, very promising, graphene ultracapacitors which are starting to emerge:

It is nevertheless gongfée to call a battery for a storage of H2.

But you tell me the function is the same.

[Obamot]

No we will not say

Because I believe NLC and Remundo would not agree

Yes and no: It is a fuel cell and it is rechargeable ...
I do not know if the electrolysis is integrated into the device, but if it is, it makes a battery: recharging by electricity, discharging by electricity ... Between the 2 stages there would be chemistry, and this is the case for any battery ...

So it would be a fuel cell

[Obamot]

To jostle with the terminology it's the journalist who talked about drums!

McPhy doesn't say exactly that!

They speak in a place of "cluster", and more precisely of storage containers in solid form,

They also say that the stored hydrogen can convert back into electricity using a Fuel cell.

Which would then be the most correct term. Note that they differentiate the storage of hydrogen in solid phase from its reconversion stage.

In the sense that they did not "invent" the fuel cell. Their domain is the storage of hydrogen, and in this sense, we cannot speak of a battery (otherwise it would be a bit like considering the fuel tank of a car as "the engine", c 'is abusive amha.)

Without speaking for him, I think that's what Lessdewatt meant.

It’s still gongfée to call a battery for a storage of H2.

Which would then be the most correct term, if we really want to talk about "battery", which they do not do. Because note that they differentiate the storage of hydrogen in solid phase of its subsequent stage of reconversion into electricity.

In the sense that they did not "invent" the fuel cell. Their domain is indeed the storage of hydrogen, and in this sense there, we cannot speak of a battery (otherwise it would be a bit like considering the gas tank of a car as "the engine", this is abusive amha.)

Without speaking for him, I think that's what Lessdewatt meant.

It’s still gongfée to call a battery for a storage of H2.

Regardless of the storage efficiency (which may be very good), that of the electrolysis and the fuel cell is poor.

I think this "battery" should not return 50% of the energy supplied
