Toyota Motor North America, Inc. (TMNA) revealed “Project Portal” – a hydrogen fuel cell system designed for heavy duty truck use at the Port of Los Angeles. Announced at a press conference with Port officials and representatives from California Air Resources Board (CARB) and the California Energy Commission (CEC), the zero-emission truck proof of concept will take part in a feasibility study examining the potential of fuel cell technology in heavy duty applications.
A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction of positively charged hydrogen ions with oxygen or another oxidizing agent.
Fuel cells are different from batteries in requiring a continuous source of fuel and oxygen or air to sustain the chemical reaction, whereas in a battery the chemicals present in the battery react with each other to generate an electromotive force (emf). Fuel cells can produce electricity continuously for as long as these inputs are supplied.
