A direct methanol fuel cell is a variant of a proton exchange membrane fuel cell that uses methanol directly without prior reforming. Methanol is converted to carbon dioxide, protons and electrons at the anode. Like a standard proton exchange membrane fuel cell, protons react with oxygen at the cathode through a proton exchange membrane, and electrons pass through an external circuit to the cathode and work.
Basic conditions Total reaction formula: 2CH4O + 3O2 + 4OH-= 2CO32- + 6H2O
Positive electrode: 3O2 + 12e– + 6H20 → 12OH–
Negative electrode: 2CH4O - 12e– + 16OH~ → 2CO32- + 12H2O
Acidic condition CH4 + 2O2 → CO2+2H2O
Positive: 3O2 + 12e– + 12H+ → 6H2O
Negative electrode: 2CH4O - 12e– + 2H2O → 12H+ + 2CO2
The battery has a desired operating temperature of 120 ° C or less, which is slightly higher than a standard proton exchange membrane fuel cell, and its efficiency is about 40%.
A direct methanol fuel cell is a variant of a proton exchange membrane fuel cell that uses methanol directly without prior reforming. Methanol is converted to carbon dioxide and hydrogen at the anode, and like a standard proton exchange membrane fuel cell, hydrogen is then reacted with oxygen.
A car`s interior door handle is a small lever that you pull to release the door`s hook from the vehicle frame`s latch. It varies depending on your vehicle make, model, or variant. Most interior car door handles are made of plastic, while some are cast metal. Further, there are designs offering a mix of both like a plastic bezel and metal lever, or vice versa.
Both materials come with different finishes, includes the usual chrome-plated, primed, smooth or textured, chrome bezel and colored lever combination, paint to match, satin chrome, and polished. In short, there is a vast selection of parts to match your old ones. The important thing is to look for the material you prefer. For example, chrome-plated parts could come either with a plastic or metal base material. You may also choose textured levers for better grip.
These vehicle-specific parts are made to match the OEM part in every way except for cost and feature:
- Stock Appearance: this replacement door handle has the same dimensions and specifications as stock, and was specifically designed to look and function the same as the original interior handle on particular vehicles.
