Cooking with hydrogen

[MCMuckle]

Hello,

I am experimenting with solar generated hydrogen for cooking purposes. Here in Kenya, like many developing countries, the majority of people cook with wood, charcoal or kerosene. This in itself is bad as the fumes and particulates are very unhealthy. Of course the deforestation is a huge problem also, causing many negative effects on the environment.

Anyway, I have put together a simple working model but am no expert in HHO so am hoping people will be able to offer some assistance and ideas for improving the design of the device. Mostly regarding optimising the hydrogen output.

Thanks

Not sure if you could take advantage of this but the other day, I read how heat can significantly improve electrolysis efficiency:

High-temperature electrolysis (also HTE or steam electrolysis) is a method being investigated for the production of hydrogen from water with oxygen as a by-product.

(...and on the same page Electrolysis and thermodynamics (
In most cases, such as room temperature water electrolysis, the electric input is larger than the enthalpy* change of the reaction, so some energy is released as waste heat. In the case of electrolysis of steam into hydrogen and oxygen at high temperature, the opposite is true. Heat is absorbed from the surroundings, and the heating value of the produced hydrogen is higher than the electric input. In this case the efficiency relative to electric energy input can be said to be greater than 100%. The maximum theoretical efficiency of a fuel cell is the inverse of that of electrolysis. It is thus impossible to create a perpetual motion machine by combining the two processes.

My guess is that you might easily be able to induce steam through an added solar water heater possibly with the aid of mirrors, prisms or lenses, which, by the way, seems to be the trend among solar panel manufacturers to improve efficiency.

I do hope others chime in as electrolysis is new to me and few are aware just how widespread and environmentally devestating such practices you describe are. In addition, you may want to search social networking sites for specific hydrogen/hydroxy/electrolysis forums or groups.

*en·thal·py /ˈenTHalpē/ Noun: 1. A thermodynamic quantity equivalent to the total heat content of a system, equal to the internal energy of the system plus the product... 2. The change in this quantity associated with a particular chemical process.

Hi,

I have some ideas about this.

(1.) Get Patrick Kelly's Pdf or better download the chapter on HHO Generation.

(2.) Create a unit that can generate HUGE quantities of HHO ON DEMAND.This cuts down storage problems.I suggest self resonant cell with extremely high surface area electrodes in cylindrical spiral geometry.Wire mesh coated with platinum or titanium might work.Just the expense.A bank of such cells might be desirable.Many Kits are available for cars so some mods might be possible to suit your application.

(3.) You said solar, so maybe you could charge batteries via photovoltaics.I know someone who made solar voltaic cells from chlorophyll extract and two panes of glass.But I need to get back to them on specifics.

Maybe this info might be helpful to you or others.I like the on demand feature, turn a knob and your hydrogen is instantly converted from water to HHO as needed.
