Hydrogen fuel cells

Hydrogen fuel cells. (Matsushita Electric Industrial Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58121566 A2 19 Jul 1983 Showa, 3 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: H01M008-06. APPLICATION: JP 82-4590 13 Jan 1982. DOCUMENT TYPE: Patent CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) H fuel cells have a concentric H storage unit with an inner and an outer compartments to operate absorption-desorption cycle in an alternate manner to use the exothermic and endothermic effects in H delivery and storage. Thus, a stacked H-O fuel used an inner concentric H storage unit filled with Ti-Mn1.5. The cell output was 0.7 ± 0.02 V in 5000-h operation and the fuel cell start-up time was ￡0.5 h.

Compensated amorphous silicon solar cell

Compensated amorphous silicon solar cell. Devaud, Genevieve (USA ). U.S. US 4409424 A 11 Oct 1983,6 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: H01L031-06. NCL: 136258000.Chemicals with cas numbers 7637-07-2 and 1333-74-0 also play role. APPLICATION: US 82-390730 21 Jun 1982. DOCUMENT TYPE: Patent CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) An amorphous Si solar cell includes an elec. conductive substrate, a layer of glow-discharge deposited hydrogenated amorphous Si (a-Si:H) over the substrate, and regions of differing cond. with 31 region of i-a-Si:H. The layer of a-Si:H has opposed 1st and 2nd major surfaces where the 1st surface contacts the elec. conductive substrate and an electrode for elec. contacting the 2nd major surface. The i-a-Si:H region is deposited in a glow discharge with an atm. which includes e0.02 at.% monoat. B. An improved n-i-p solar cell is disclosed using a BF3-doped i layer. Thus, the resp. efficiency, fill factor, open-circuit voltage, and short-circuit c.d. for a n-i-p cell (area = 0.062 cm2) with a BF3-doped i layer were 3.02%, 0.565, 0.804 V, and 6.64 mA/cm2 vs. 2.10%, 0.425, 0.701 V, and 7.03 mA/cm2 for a p-i-n solar cell (area = 0.066 cm2) using an undoped i layer. .
