Abstract:
A method of using a non-toxic fuel cell to heat a food item located in a chafing dish, the method comprising the steps of:providing a chafing dish having an underlying fuel cell cavity;filling a container, opened at one end, with a non-toxic combustible medium consisting essentially of pure propylene glycol;embedding a wick within the non-toxic combustible medium consisting essentially of pure propylene glycol and at least partially extending the wick out through the opened end of the container to facilitate igniting the wick and combustion of the non-toxic combustible medium consisting essentially of pure propylene glycol within the container;placing the container with the non-toxic combustible medium consisting essentially of pure propylene glycol in the at least one underlying fuel cell cavity; andigniting the wick to burn the non-toxic combustible medium consisting essentially of pure propylene glycol and heat the food item located in the chafing dish.
