This is obviously incorrect, but the final calculation does in fact multiply the efficiencies.

Hydrogen from water electrolysis is clean and green. It is a solution for renewable variability and values excess energy supply. The electrolyzer used at the Phi Suea House is the most cost efficient on the market, and can handle intermittent renewable energy supply.

Yet today, as battery electric vehicles are starting to gain appreciable acceptance in the mainstream marketplace and static battery energy storage products are starting to flood the market, hydrogen fuel cell technology seems to be struggling to grow at all. How were analysts were wrong? What advantages do battery packs have over hydrogen fuel cells? And what does it mean for the future of both transportation and energy storage?

For hydrogen fuelling stations, Linde has developed a 5-stage ionic compressor. The pistons of the machine move up and down hydraulically. On the top of the pistons there is the ionic liquid which is compressed through the compressor cylinder as a "liquid piston" together with the hydrogen. At the end of the compression process the ionic liquid is separated from the hydrogen by the separators and returned to circulation. This design results in less wear and tear as well as much higher energy efficiency thanks to optimized cooling and avoidance of parasitic volume during the compression process. Compared to a conventional piston compressor, energy savings is around 40%.

The purpose of this dissertation is the study, the analysis and the modeling of a Proton Exchange Membrane fuel cell (PEMFC). This type of fuel cell has been chosen because it is the most promising candidate for replacing the internal combustion engine in automobiles, for lower power CHP systems, and for replacing batteries in portable and micro applications. Specifically, there is a need to investigate the most important factors that influence the fuel cell's performance using a 3D Computational Fluid Dynamics (CFD) analysis, taking into account simultaneous multi-component, multi-phase, multi-dimensional fluid flow with heat and mass transfer as well as and electrochemical reactions. The first aim of this investigation is to select an appropriate geometry of a PEM fuel cell accompanied with experimental results, simulate the chosen geometry and produce similar results using the commercial CFD software FLUENT in order to validate the simulation procedure. Finally, the parametric studies are applied which help to discover new behaviors in order to optimize the performance of the fuel cell.
Honda's guide to how the technology in its hydrogen fuel cell production vehicle - the FCX Clarity - works.
"Fuel cell cars, which run on electricity produced from compressed Hydrogen, emit zero harmful emissions and could be the future of motoring. They can be just as fast, practical, and can travel as far as a conventional petrol or diesel engine car, but the technology is very different. And importantly, the only thing that comes out of the exhaust is water vapour.
Rather than having a petrol or diesel tank like a conventional car, the fuel cell car has a tank that stores compressed Hydrogen as a gas. Hydrogen is used as an energy carrier, so that the fuel cell car can produce its own electricity onboard, rather than storing it in batteries.
This compressed Hydrogen is expanded and then fed into the fuel cell stack. The fuel cell stack is like a tiny electric power station. Inside it, the Hydrogen combines with Oxygen from the air to generate electricity and water as a byproduct. Water vapour is the fuel cell car's only emission.
The electricity created inside the fuel cell stack is used to power the electric motor, which is, in turn, used to drive the car. The fuel cell stack is made up of hundreds of individual cells stacked together like a loaf of bread. In fact, each cell is like a sandwich, with a Membrane Electrode Assembly (or MEA) between two separators (or Bi-Polar plates). The MEA is made up of a Proton Exchange Membrane, or PEM, which sits between Hydrogen and Oxygen electrode layers and gas diffusion layers.
In each cell, Hydrogen gas passes over the Hydrogen electrode. Each Hydrogen atom is converted into a Hydrogen ion in a catalytic reaction, releasing an electron in the process. The Hydrogen ions then pass through the electrolytic membrane, where they bond with Oxygen ions straight from the atmosphere. The previously emitted electrons from the Hydrogen molecules arrive at the Oxygen electrode via an external circuit. The released electrons create a flow of direct electrical current in the external circuit, and water is generated at the Oxygen electrode as a byproduct. This water is drained from the system and exits the car as water vapour via the exhaust.
Because the electricity is generated from Hydrogen and Oxygen, no Carbon Dioxide or other polluants are emitted from the car. It's the ultimate in clean performance.
