Abstract
A fuel cell system comprises a fuel cell, a fuel gas passage through which a fuel gas containing an odorant and hydrogen gas supplied to the fuel cell flows, an oxidative gas passage through which an oxidative gas supplied to the fuel cell flows, a fuel off gas passage through which a fuel off gas discharged from the fuel cell flows, an oxidative off gas passage through which an oxidative off gas discharged from the fuel cell flows, and an odorant removal portion provided in the fuel off gas passage. The odorant removal portion removes the odorant after the fuel gas has been introduced into the fuel cell.
Claims21
A fuel cell system comprising:
- a fuel cell;
- a fuel gas passage which is connected to the fuel cell and through which a fuel gas containing an odorant and hydrogen gas supplied to the fuel cell flows;
- an oxidative gas passage which is connected to the fuel cell and through which an oxidative gas supplied to the fuel cell flows;
- a fuel off gas passage which is connected to the fuel cell and through which a fuel off gas discharged from the fuel cell flows;
- an oxidative off gas passage which is connected to the fuel cell and through which an oxidative off gas discharged from the fuel cell flows;
- and
- an odorant removal portion which removes the odorant from the fuel gas after introduction of the fuel gas into the fuel cell.
A fuel cell system comprising:
- a fuel cell which is provided with an opening portion and which generates electricity by means of an oxidative gas and hydrogen gas that has been introduced via the opening portion;
- a fuel gas passage which is connected to the opening portion of the fuel cell and through which a fuel gas containing hydrogen gas and an odorant is supplied to the fuel cell;
- and
- an odorant removal portion provided downstream of the opening portion.
