Today, fuel cells are being developed to replace the internal combustion engine in motor vehicles, to provide electricity for commercial and domestic buildings, and to power small electric devices, such as mobile phones and computers.
Dewasa ini, sel bahan bakar sedang dikembangkan untuk mengganti mesin pembakaran internal dalam kendaraan bermotor, menyediakan listrik bagi bangunan komersil dan rumah tangga, serta mentenagai alat elektronik kecil, seperti ponsel dan komputer.
