Carbon monoxide is evolved (burns with a blue flame forming carbon dioxide) poisonous gas. 

Carbon dioxide is a simple asphyxiant that is, it causes toxicity by displacing oxygen from the breathing atmosphere primarily in enclosed spaces and results in hypoxia. It has been postulated that the cause of death in breathing high concentration of carbon dioxide is due to carbon dioxide poisoning and not hypoxia based on a study performed in dogs.

Although the harmful effects of carbon dioxide poisoning can be partly reduced by circulating the electrolyte as discussed by Cifrain et al. (2003b), a permanent solution must be sought for possible commercialization of alkaline fuel cell.
