There are 3 main types of a Fuel Cell. 1. Hydrogen Fuel Cell. This is the main one people use nowadays. 2. Solid Oxide Fuel Cell. 3. Alkaline Fuel cell. Made from Alkaline metals.
Hydrogen Fuel Cell converts the thermal energy released directly into electrical energy.. This fuel cell was used in the Apollo Programe. It also produces water.....
Proton Exchange Membrane Fuel Cells are used for both stationary and portable applications. Advantages such as high current densities, fast start-up times and compactness of design makes this type of fuel cell a very attractive and promising candidate for automotive and portable applications.
If you mean Aluminum metal, then answer is No. This is because aluminum will dissolve in alkali as aluminate ions.

Probably an increase in technology that used alkaline cell batteries
potang ka potang ina mo !!
A fuel cell oxidizes a fuel source, a standard cell is an electrochemical reaction.
Fuel cells come in many varieties. Low-temperature designs such as proton exchange membrane fuel cells [PEMFC's, also known as polymer electrolyte membrane fuel cells] are mostly aimed at portable and transport applications
Oxygen, nitrogen and alkaline
No, a lead acid battery is a wet cell battery and a 9 volt alkaline battery is a dry cell battery.
I am not able to give you a cost, as there are a number of fuel cell technologies, and it will be difficult to know which ones might ultimately become commercial. So far, fuel cells applications have required large government subsidies. The "hydrogen car" is still apparently a long ways from becoming a reality- see related links.
