Application 10/810,960
1 The Prior Art: Okamoto
2 4. With reference to Figure 1, reproduced here,
3
4 Okamoto discloses a fuel cell system comprising:
5 (a) a fuel gas supply device 10 comprising a methanol tank 12 that delivers
6 methanol to a reformer 14 (Okamoto at col. 2, ll. 45–51), which in turn delivers hydrogen
7 to a hydrogen gas supply 16, which comprises a hydrogen selective permeable membrane
8 58, which selectively allows penetration of hydrogen gas only (id. at col. 3, 24-28). The
9 hydrogen gas is then directed through conduit 20 to the hydrogen electrode 40 (anode)
10 side of fuel cell 30. (Id. at col. 2, 59-67.) A water tank 24 provides water to the reformer
11 14 and to the hydrogen gas directed at the anode via conduit 22. (Id. at col. 2, ll. 55–60);
12 (b) an air delivery system comprising a blower 46, which directs air to the air
13 electrode 30 (cathode) of the fuel cell;
