Implication

Experimental study reveals increased power density in microfuel cells using phosphorus-doped silicon dioxide, indicating its viability as a thin-film proton exchange membrane.

Key Points

To evaluate the feasibility and electrochemical performance of phosphorus-doped silicon dioxide thin films as proton exchange membranes in microfabricated fuel cells.
Synthesized phosphorus-doped silicon dioxide (PSG) thin films at low temperatures using plasma-enhanced chemical vapor deposition (PECVD).
Characterized the ionic conductivity and area resistance of the PSG films, comparing their resistance directly against standard Nafion films.
Integrated the PSG thin films as proton exchange membranes into microfuel cells to quantify changes in cell power density.
Phosphorus doping increased the ionic conductivity of low-temperature deposited silicon dioxide films by more than three orders of magnitude.
Microfuel cells incorporating PSG proton exchange membranes yielded more than one order of magnitude higher power density compared to cells with undoped membranes.
The area resistance of the deposited PSG thin films remained comparable to that of conventional Nafion films.
