Why Is the Promise of Fuel Cells Still Unfulfilled?

Click For Summary

Discussion Overview

The discussion centers around the challenges and limitations of fuel cell technology, particularly focusing on hydrogen as a fuel source. Participants explore various aspects including economic factors, efficiency, and infrastructure related to hydrogen production and storage.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant expresses initial enthusiasm for fuel cells, highlighting their potential to combine hydrogen and oxygen to produce water without waste.
  • Another participant lists several challenges including hydrogen storage, efficiency of hydrogen production, overall process efficiency, high costs of fuel cells compared to traditional engines, and the need for infrastructure to manufacture and distribute hydrogen.
  • A clarification is made regarding the production of hydrogen, noting that it must be manufactured from other sources, which raises concerns about energy efficiency since the process of generating hydrogen from water does not yield a net energy gain.
  • A participant acknowledges that the progress of fuel cell technology has slowed due to these economic and technical hurdles.

Areas of Agreement / Disagreement

Participants generally agree that there are significant economic and technical challenges facing fuel cell technology, but no consensus is reached on how these issues might be resolved or the future of the technology.

Contextual Notes

Limitations include the dependence on the definitions of efficiency and cost, as well as the unresolved nature of the energy balance in hydrogen production.

About an year ago, i had heard a lot about the upcoming technology of fuel cells. i was pretty intrigued by the description that it combined, hydrogen and oxygen to form pure water. no wastage. i believed it would be the alternative fuel we were in search of.
why then is there not much progress in this field.
is there any site giving constructional details of the fuel cell

:confused:
 
Engineering news on Phys.org
- Hydrogen storage
- Efficiency of hydrogen production
- Efficiency of net process from production of H2 to actual work done
- High cost of fuel cells (10 times costlier than the piston)
- Hydrogen manufacture and distribution infrastructure
- Cost of Hydrogen
 
As sid implied, there are a number of mostly economic hurdles that need to be overcome (perhaps with technology) before it becomes mainstream.

A clarification: since hydrogen does not occur naturally in usable quantities, it must be manufactured, either from water or from methane. Since getting it from water is the same reaction by which it creates electricity, running in the opposite direction, there is no net gain of energy: it is just a storage method.
 
i get it so the momentum of the project has slowed down due to the hurdles that have been coming up.
