What is the diffence between a hydrogen fuel cell and a hydrogen combustion engine?

A hydrogen combustion engine is like the engine in your car. Hydrogen and oxygen enter a combustion chamber, ignite, and form a ball of hot vapour (steam) which moves a piston that rotates a crankshaft. Alternately a hydrogen combustion engine could be a rocket or jet engine where the burning fuel exhausts the combustion chamber as vapour (steam again) and impacts a forward motion to the engine by the mass discharge.
A fuel hydrogen cell is more like a battery. Hydrogen and oxygen react in a catalyst matrix that allows the process to continue at a fixed rate. Like most chemical reactions this involves the movement of electrons to create positive and negative reactant ions. The flow of electrons is conducted to an electrical system as power. Water is still the byproduct.

What is the difference between internal combustion engine and heat engine?
Can water be used as fuel in internal combustion engine?
Today - no. But they are working on it. If they can find a way to efficiently separate the hydrogen from the oxygen you can run a vehicle on the hydrogen.
What engine is an example of an internal combustion engine?
The four-stroke engine used in automobiles is an example of an internal combustion engine.
What is a sentence for combustion?
Example sentence - The combustion engine is an amazing piece of machinery.
Is the internal combustion engine's fuel burns outside the engine in chambers called cylinders?
Internal combustion refers to an engine were the combustion process takes place inside the engine. The cylinders in question are an internal portion of the cylinder block which houses the crankshaft, connecting rods and the pistons which move up and down in the cylinder drawing in the air fuel mixture, are forced down by the combustion process, and push the spend fuel charge out of the cylinder at the end of the cycle. An example of an external combustion engine would be a steam engine where the combustion takes place in a boiler external to the engine and the steam generated by the boiler is used to motivate the engine.
Hydrogen in internal-combustion engine?
no
How do motors on hydrogen cars differ from combustion or hybrid engines?
Like a gas combustion engine, a hydrogen engine relies on the combustion process - in this case, combustion that results when hydrogen is combined with oxygen. Fuel cells in a hydrogen-powered car then convert this mechanical energy into electrical energy.
What is the most important difference between and internal combustion engine and an external combustion engine?
in internal combustion engine combustion happens internally in cylinder and in external combustion engine combustion happens externally in boiler
What is the most important difference between an international combustion engine and an external combustion engine?
in internal combustion engine combustion happens internally in cylinder and in external combustion engine combustion happens externally in boiler
Can a jet engine be powered by hydrogen combustion?
Yes. See link below.
Difference between diesel engine and old steam engine?
The main difference between a diesel and a steam engine is the diesel engine is an internal combustion and the steam engine is external combustion.
How can you tell the diffence between a 351 and a 302 ford v8 engine?
the 351 intake is wider
What is the difference between internal combustion engine and heat engine?
What is the difference between an external combustion engine and internal combustion engine?
An external combustion engine is where something is burning outside of the actual engine and the energy is transmitted to the engine via something. (e.g. boiler creates steam that goes to the engine a.k.a. steam engine) In an internal combustion engine, the burning happens in the actual cylinders of the engine. (e.g. car engine)
How is the BMW 7 series different than other BMWs?
The BMW 7 Series is different from other BMWs in that it is a modified version of other BMW models as it allows for the combustion of hydrogen and gas, both. The difference between the BMW 7 series and other hydrogen powered vehicles produced by other companies, is that it burns the hydrogen in an internal combustion engine.
What types of engine does NOT use atmospheric air for combustion?
Hydrogen can, especially in the case of electrical hydrogen production as the process creates it's own oxygen
Can water be used as fuel in internal combustion engine?
Today - no. But they are working on it. If they can find a way to efficiently separate the hydrogen from the oxygen you can run a vehicle on the hydrogen.
